Faultfinding and magnifying the defects and weaknesses of others, is among the many sins which, in addition to the punishment of the hereafter, will have a worldly punishment as well, there is a narration from Imam Sajjad (peace be upon him) that says: the one who keeps faultfinding and reproaches people with these defects and faults, he will be accused with the defects which don’t exist in him.
