SHAFAQNA – Imam Sadeq (AS) said: No prophet has been appointed except for truth and returning the deposit to good doer or bad doer . Imam Ali (AS) said: I swear to God that I heard moments before passing away, the Prophet repeated 3 times: O’ Abolhassan, return the deposit to good doer or bad doer, be it little or a lot, even if it is thread and needle . In another narration the Prophet (PBUH) said: Return the deposit even to killers of the prophets .
