Hazrat Moulana Muhammad Ilyaas (rahmatullahi ‘alaih) mentioned:
The first and most important demand of deeni knowledge which one acquires is that it should serve as a means to assist one in taking stock of one’s life and becoming conscious of one’s deeni obligations and responsibilities towards Allah Ta‘ala and the creation. It should be a means for one to realize one’s weaknesses and shortcomings and create the desired level of concern to correct and reform one’s character and ways. However, if the deeni knowledge one acquires does not enable one to see one’s own weaknesses and look for solutions to correct oneself, but instead becomes a means of searching for the faults in people’s actions and scrutinizing their lives, then the outcome of such knowledge is that it will breed pride and haughtiness within a person. This in turn will lead to one’s destruction. (Malfoozaat Hazrat Moulana Muhammad Ilyaas
