“Beware of suspicion, for suspicion is the worst of false tales and do not look
for the others' faults, and do not do spying on one another, and do not practice
Najsh (to cheat), and do not be jealous of one another and do not hate one
another, and do not desert (stop talking to) one another. And O, Allah's
worshipers! Be brothers!"
Sahih Al-Bukhari Volume 008 Book No. 073 Hadith No. 092 Narrated by Abu Huraira (r.a.)
