Yahya related to me from Malik from Abu'z-Zinad from al-Araj from Abu Hurayra that the Messenger of Allah ﷺ said, "Beware of suspicion. Suspicion is the most untrue speech. Do not spy and do not eavesdrop. Do not compete with each other and do not envy each other and do not hate each other and do not shun each other. Be slaves of Allah, brothers."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِيَّاكُمْ وَالظَّنَّ فَإِنَّ الظَّنَّ أَكْذَبُ الْحَدِيثِ وَلاَ تَجَسَّسُوا وَلاَ تَحَسَّسُوا وَلاَ تَنَافَسُوا وَلاَ تَحَاسَدُوا وَلاَ تَبَاغَضُوا وَلاَ تَدَابَرُوا وَكُونُوا عِبَادَ اللَّهِ إِخْوَانًا
