Abu Hurayra reported that the Messenger of Allah ﷺ said, "Beware of suspicion. Suspicion is the worst type of lie. Do not spy. Do not fight one another. Do not try to ensnare one another (in sales). Do not envy each other. Do not hate one another. Be slaves of Allah and brothers."

أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِيَّاكُمْ وَ الظَّنَّ فَإِنَّ الظَّنَّ أَكْذَبُ الْحَدِيثِ وَلاَ تَجَسَّسُوا وَلاَ تَنَافَسُوا وَلاَ تَدَابَرُوا وَلاَ تَحَاسَدُوا وَلاَ تَبَاغَضُوا وَكُونُوا عِبَادَ اللهِ إِخْوَانًا

Avoid suspicion for suspicion is the most lying form of talk. Do not be inquisitive about one another, or spy on one another.

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِيَّاكُمْ وَالظَّنَّ فَإِنَّ الظَّنَّ أَكْذَبُ الْحَدِيثِ وَلاَ تَحَسَّسُوا وَلاَ تَجَسَّسُوا

"Beware of Zann (suspicion), for indeed Zann is the falsest of speech."

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِيَّاكُمْ وَالظَّنَّ فَإِنَّ الظَّنَّ أَكْذَبُ الْحَدِيثِ

Messenger of Allah ﷺ said, 'Beware of suspicion, for it is the worst of false tales and don't look for the other's faults and don't spy and don't hate each other, and don't desert (cut your relations with) one another O Allah's slaves, be brothers!" (See Hadith No. 90) (Using translation from Bukhārī 6724)

قَالَ رَسُولُ اللهِ ﷺ إِيَّاكُمْ وَالظَّنَّ فَإِنَّ الظَّنَّ أَكْذَبُ الْحَدِيثِ

قَالَ قَالَ رَسُولُ اللَّهِ ﷺ إياكم والظن فإن الظن من أكذب الحديث
