Here this question is being studied under the heading of "The causes of the decline of the Muslims". This heading includes various subjects, events and questions, namely historical, psychological, moral, social and religious.
The only link which binds these subjects together is their positive or negative effects on the progress and the decline of the Muslim society. The aim here is to see whether a belief in destiny as required by philosophical reasoning is one of those ideas which lead its adherents to lethargy.
Are the believers automatically dragged to decline and decay or is it a doctrine which has no ill effect if it is expounded in a sound manner. Here we will see how Islam has presented this question and with what effect on its followers.
