A religious man...
A religious man, with firm belief in Allah, and of His munificence, does not find himself in utter desperation even in the worst moments of his life, because he knows well hat e is under the protection of a Being who is Almighty. With faith in the fact that every problem can be solved and every deadlock can be resolved with His help, he can overcome every disappointment and hopelessness.
For this very reason, it very seldom happens that a truly religious man suffers from the acute reactions of desperation like suicide, nervous breakdown or psychic ailments which are products of frustration and defeatism.
The Holy Qur’an says: "Surely those who are close to Allah, have no fear nor shall they grieve." (Surah Younus, 10:62) Imam Ja’far as-Sadiq (A) says: "A true believer can never commit suicide." Thus, religious faith is, on the one hand, a motivating force, and on the other, it is a factor which enables man to face hardships with courage and saves him from the ill effects of failure and disappointment.
Following the downfall of the Nazis, says Bertrand Russell says there existed a danger of intellectual and ideological revolt in Germany, but no doubt, religion has been one of the biggest factors in that country's return to stability. According to Dr. Durant, behavior of a man who is not blessed with reliance on religion suffers from special epicurean confusion, and the life which has not the comforting support of religion, is an unbearable burden.
Encounter with Ideological Vacuum Man cannot live in an ideological vacuum for long and as such his tendency towards a wrong ideology and false values becomes definite. His intellectual life is not filled with sound beliefs and healthy teachings. A superstitious and even destructive ideas may find way into his spiritual firmament and may for ever pollute his brain.
Instances of man's tendency towards idolatry, man worship, diverse superstitions and credulity regarding the influence of irrational things over destiny, can be witnessed even in the lives of world intellectuals. All this originates from spiritual vacuum. It is religion which can fill the ideological and intellectual vacuum with sound teachings and can save one from a tendency towards absurdities and irrationalities.
Hence, true understanding of religion can play an important role in combating superstitions, though it is true that even religion itself, if not understood correctly, may promote superstitions.
