It is a fact that the circumstances were conducive for atheism to make its home by intruding into several Muslim countries. The following are some of explanation of circumstances and causes that prevail in those countries:-
(1) Deviation of several Muslims from the right Islamic teachings and their (Muslims) shunning away of a good part of the Divine Message sent to them.
The perseverance, tolerance and fear of Allah and the consciousness about His eternal presence are some of the factors that would guarantee to the denial of falsehood
Allah state in the Qur an:
 وَإِنْ تَصْبِرُوا وَتَتَّقُوا لاَ يَضُرُّكُمْ كَيْدُهُمْ شَيْئاً
“But if you remain patient and become the pious, not the least harm will their cunning do to you." [Surah Aal  Imran 3:120].
(2) Defeat and surrender of the Islamic world to the European cultural onslaught and their propaganda about the material life. The US and Europe are holding the power over materialistic life with a supremacy of machines, building and the factories.
Thereafter, they (West) have turned the Third World countries as a platform for marketing and promoting their industrial products. What a pity it is that they acquired the unprocessed raw material from the Third World, as required for their industrial machines [and we (the Muslim world) receive the finished products against the payment of exorbitantly high prices].
In fact, countries in the Muslim world have become the dumping ground for their products and we have been accustomed to use the luxurious machines, be they vehicles, home appliances or airplanes produced in the Western countries, thus boosting their revenues and economies.
Besides, these countries acquire what they wanted from us against the payment of meager price, you term it as their greediness or the arrogance. They also make us target of their military might.
It would be a bitter pill but the Muslim world has to swallow since the Muslim countries cannot stand firm on their foot because of their weakness in the military power and political inactivity.
Accordingly, our weakness in many fields including military has been effecting and influencing the thinking as regards to the concept of belief, which stood shaken.
This fact could be seen being reflected in the behavior of our youths who blindly imitating the Western culture and mostly tend to behave in the similar manner as the Western do. This is indeed a decline in the character and moving from the morale values as shown to us in the Islamic teachings.
These ignorant Muslims, under the influence of fast spreading Western culture, are being deviated from the true Islamic teachings. How could they preserve their own culture when they are engaged blindly to follow the Europeans and West?
They false realized that that the Europe has made tremendous progress and development only after turning themselves into atheism by rejecting their own religious values.
(3) Western hegemony is fast spreading in several Muslim countries. Many Muslims have already faced troubles in the hands of colonialist and imperialist while the West is involved in sucking Muslims’ blood and siphoning away their God-given bounties, properties and land as well.
(4) Concentration and prevalence of Westerners are corrupting the educational and media systems among the Muslim countries. They also engaged in corrupting the Muslim women as well as deforming and tarnishing the true image of Muslim scholars.
They are also enthusiastic in spreading the free sex under the garb of liberalism. The pornography as well as nudity is freely spoken without any shame of scrupulous behavior.
Several Muslim youths have become the target of this sordid behavior and the situation is proving as a quagmire for those who are still in the midway of right and wrong. The atheism will not germinate or sprout overnight except a similar atmosphere prolongs for a certain period.
(5) The decline is being noticed in the establishment of allegiance of creed with that of the ruler. Otherwise, the system would fail as majority of Muslims adopt to the innovative practices.
(6) The increase and spread of other perspectives thus ignoring the teachings of Islam.
(7) The spread of the factions who are involved in destructive and devastative practices and those of strayed and misguided sects. Others categories included the humiliated path of the Sufis (Ascetics) as organized by quack based on superstitions, grave-worshippers, extremists engaged in spreading news about the unusual and incredible happenings by the so-called saints.
These factors and methods would indeed facilitate those who possessed superficial knowledge about Islam and lead them to become atheists while the disbelievers would exploit the situation as an opportunity to commit blasphemy against the religion.
(8) Some Muslims going abroad to non-Muslim countries on deputation return back with corrupt and malicious mentality. They (Muslims) being unaware of the effect of the alien culture and practices slowly start to behave by imitating the non-Muslims thus losing their piety and fear of Allah
Non-Islamic practices attract Muslims forcing them to adopt their false ideologies, knowingly or unknowingly they become influenced and return to their country after acquiring a prestigious doctorate degree but with a weaken faith in Allah.
Even worse that, in some cases these people with doctorate degrees show laxity to the importance of even the divine testimonies of faith that there is no deity worthy of worship except Allah.
(9) Constant failure or frequently imperfect preaching of the Islamic teachings leading to the incorrect practices and ultimately deviation from the Way of Allah.
(10) Other factor is the breakdown of the Islamic caliphate system.
(11) Muslims ignorance from an obligatory duty in Islam to wage Jihad against the growing infidelity for the sake of Allah is another factor. Instead of this, the Muslims sought to lead a luxurious life, entertaining in the comforts and ease of their worldly life.
CONSEQUENCES OF ATHEISM:
Both individuals and the societies suffered a set serious set back because of atheism and disbelief. The nations in the non-Islamic countries are living a pathetic situation leading a difficult life. They (disbelievers) seldom find a bold solution for their problems and consequently live in constant fear and disharmony.
Not only in this worldly life, they face the torment of mind, grievous punishments also await them on the Day of Judgment by Allah. They would stand losers at the both ends and their final abode would be the Hell-Fire, if they died as disbelievers.
The following are some of the evil consequences of atheism.
(1) The state of mind of such people would be the psychological anxiety, worry, concern, mental disorder, and or losing of mental peace altogether.
Allah stated in the Qur an:
وَمَنْ أَعْرَضَ عَنْ ذِكْرِي فَإِنَّ لَهُ مَعِيشَةً ضَنْكًا وَنَحْشُرُهُ يَوْمَ الْقِيَامَةِ أَعْمَى
“But whosoever turns away from My Reminder (i.e. neither believes in this Qur ân nor acts on its orders, etc.,) verily, for him is a life of hardship, and We shall raise him up blind on the Day of Resurrection." [Surah Ta-Ha 20:124].
If this is the warning from Allah, just imagine: How could a person expect that atheism not inflict his mind with worry, anxiety, grief, sorrow, and disturbance or unrest?
How would a person even think that atheism not put his inside with full of questions of bewilderment? Who has created the life? What is the end of life? What is the beginning of life? What are the mysteries of the spirit, which after departing from a person body leave him/her motionless like an inanimate?
Where would you find answers to these questions? Is there any ideology, which could provide answers to these questions? Do you think the Communists and atheists have the solution to these questions?! How could it be possible?
Under the burden of busiest life a person hardly have time to find answers to these question though for a while he/she tries to evade such feelings. Nevertheless, for how long, the mind lingers in the same mood would start to find the solution again. In search of solutions a person unceasingly becomes restive and tries to seek solace of life.
Moreover, with this state of mind and upon not finding the right answer he/she seeks calm their soul by taking drugs and narcotics. After sometime they become addicted to such a practice. This is obviously an evidence of such a consequence.
However, the anxiety of a person does not disappear even after becoming an addict. Therefore, the worst happens that he/she would ultimately decide to take his/her own life by committing the suicide. This is the reason why we are seeing the growing number of suicide cases today.
(2) People become self-centered by focusing on their own selves. The false image about one’s own importance grows leading to a factor called individualism, which in turn directs to selfishness. The fact of their lives is that every such person engages in his own affairs.
Therefore, they start to lose feelings such as mercifulness, leniency, affection and the noble qualities of showing tenderness to others.
However, Islam encompasses all these kinds of mercies and affections.
The Prophet Muhammad (peace and blessings be upon him) said:
لاَ يُؤْمِنُ أَحَدُكُمْ حَتَّى يُحِبُّ لأَخِيهِ مَا يُحِبُّ لِنَفْسِهِ رواه البخاري رقم (13) ومسلم رقم (45).
“None among you will attain the Faith until he loves for his (believing) brother what he loves for himself (of good).” [Al-Bukhari and Muslim].
(3) A person feels thrilled and excited to commit crimes. This needs no proof to explain, since the reality of the life in the West is self-explanatory, which shows the ratio of robbery, theft, kidnapping, and several other criminal and similar whole gamut of activities.
(4) The tendency of a person for the demolition of family system: Clear proofs are available that the unbelieving societies that the families are leading a disintegrated, estranged, alienated, and or scattered lives.
(5) The corruption of the society: This is because the entire community becomes corrupted with the corrupt practices that exist in each family.
(6) The ultimate desire is to end one’s own life. This results in suicidal tendency just to escape from the realities of life. The body and mind become weak as a result of persistently prevailing faithlessness.
However, the strangest part of this reality that most of such people are of the wealthy background, which does not even suggest that the persons have committed the crime of suicide because of poverty.
Rather most of the people, who commit suicide are from the rich and professionals living a luxurious life. It is so surprising to note that these people include doctors.
Even worst to know that they are not only the general practitioners, but also include the psychiatrists, whom people trusted guessing that these are the professionals who advise their patients with psychological disorders as how achieve the ultimate happiness in life.
(7) The tendency, which leads to a strong will to take revenge and a desire to eliminate everyone.
(8) The spread the hatred, rage, and hate.
(9) Loss of trust and sincerity among such people. The person becomes afraid of his even near and dear ones.
The strong evidence in this regard was seen in the East Germany during the time when the communist ideology collapsed. People with their lost trust have visited the different police stations and detective departments to check what has been recorded about them during the spying and espionage operations in the country.
Thereupon many people have found that the one who registered a criminal case against him was his/her own mother, or sister, wife, or a close friend.
(10) Spread of illusion or delusion and frightening things.
(11) Increase in the political delinquency or criminal behavior. This is the most dangerous part of atheism. It is because of the fact that atheistic and materialistic lifestyle influence the heart of people with severity and hardness. With this tendency he/she defends such policy and tries to implement such things into action.
This is why, we have seen that the so-called superpowers of the world react to their colonized countries with humiliation, outrage, killing and displacement.
What a most subtle evidence in this regard is the cruelties of communist Stalin, during his rule from 1930 to 1952, over 30 million people were murdered during that period.
The above-mentioned facts and figures are some of the brief traits of atheism which contribute only to the devastation of the society.
From the above discussion, we reached to a conclusion that the extent of a person’s (he/she) wayward lifestyle such as going astray from the straight path as shown in the divine mission decides his/her state of mind and thus losing spirituality.
If there is a little deviation from the right path and he/she was able to mend his/her ways immediately, would help such a person a great deal in leading a decent and peaceful life.
In addition, we can conclude that people are in the dire need of true way of life and divine guidance so that they can lead their lives into definite happiness and ultimate bliss, which could be acquired only from the Islamic teachings.
However, this can be achieved through the tireless endeavor and hard struggle by preaching and practicing the correct Way of Allah.
This could be done by explaining the beauties and virtues of Islam, which confront head on with the suspicions that exist in atheism and its confusing ways.
Every care should be taken to rise the people based on the true concept of divine faith and belief as well as to train them to face the challenges of life with the upright behavior and noble characters. This is the basis as illuminated in divine revelations.
Allah will surely lead those who seek His help with true guidance. With His will, Allah has already shown guidance to the people who have already proceeded on the path performing righteous deeds with piety and faithfulness.
Allah’s peace and blessings be upon our Prophet Muhammad, his family members, and Companions, as well as upon those who follow them until the Day of Judgment. Amen!
