From Sahih Bukhari (Hadith 6064):
Narrated Abu Huraira:The Prophet (ﷺ) 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 worshipers! Be brothers (as Allah has ordered you)
