عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِيَّاكُمْ وَالظَّنَّ فَإِنَّ الظَّنَّ أَكْذَبُ الْحَدِيثِ وَلَا تَجَسَّسُوا وَلَا تَحَسَّسُوا وَلَا تَبَاغَضُوا وَلَا تَدَابَرُوا وَلَا تَنَافَسُوا وَكُونُوا عِبَادَ اللَّهِ إِخْوَانًا
Syedna Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Beware of suspicion, for indeed suspicion is the most false of speech. Do not spy, do not pry, do not harbor enmity among yourselves, avoid mutual severance and hostility, do not compete with one another, and O servants of Allah! Become brothers to one another.
