Read the English translation first, with the original Arabic directly underneath.
Narrated Abu Huraira:
Allah's Messenger (ﷺ) said, "Beware of suspicion, for suspicion is the worst of false tales. and do not look for the others' faults, and do not do spying on one another, and do not practice Najsh, and do not be jealous of one another and do not hate one another, and do not desert (stop talking to) one another. And O, Allah's worshipers! Be brothers!"
إِيَّاكُمْ وَالظَّنَّ، فَإِنَّ الظَّنَّ أَكْذَبُ الْحَدِيثِ، وَلاَ تَحَسَّسُوا، وَلاَ تَجَسَّسُوا، وَلاَ تَنَاجَشُوا، وَلاَ تَحَاسَدُوا، وَلاَ تَبَاغَضُوا، وَلاَ تَدَابَرُوا، وَكُونُوا عِبَادَ اللَّهِ إِخْوَانًا
