Narrated by Abu Huraira (Radi-Allahu 'anhu):

The Prophet (Sallallahu 'Alaihi Wa Sallam) said, "Beware of suspicion, for

suspicion is the worst of false tales; and do not look for the others'

faults and do not spy, and do not be jealous of one another, and do not

desert (cut your relation with) one another, and do not hate one 

another; and O Allah's worshippers! Be brothers (as Allah has ordered 

you!")
