Sidi wa sanadi Hazrat Moulana Mohammad Taqi Usmani sahib db said;

“Whenever one of us becomes increasingly religious his first priority becomes correcting other people. This similitude is that of a person with lethal cancer who is worried about some one else’s common cold. One who himself is severly afflicted (with muhlekat-e-nafs) never cares about other’s minor aliment. The problem is that we do not know our diseases as yet. Once we find out the deadly diagnosis all of these sermons for-others, hurting comments, slander and back-biting will disappear.”

For this diagnosis one has to approach the spiritual physicians/The Sheikh.
