حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ عَنْ مَالِكٍ عَنْ أَبِي الزِّنَادِ عَنْ الْأَعْرَجِ عَنْ أَبِي هُرَيْرَةَأَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِيَّاكُمْ وَالظَّنَّ فَإِنَّ الظَّنَّ أَكْذَبُ الْحَدِيثِ وَلَا تَحَسَّسُوا وَلَا تَجَسَّسُوا

Narrated to us [Abdullah bin Maslamah] from [Malik] from [Abu Az Zinad] from [Al A'raj] from [Abu Hurairah], that the Messenger of Allah, peace and blessings be upon him, said: 'Avoid suspicion, for suspicion is the worst of false talk. Do not pry into (others’ faults) nor spy on one another.'
