Abu Huraira reported Allah's Messenger (ﷺ) as saying. Don't nurse malice against one another, don't nurse aversion against one another and don't be inquisitive about one another and don't outbid one another (with a view to raising the price) and be fellow-brothers and servants of Allah.
حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا جَرِيرٌ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي، هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ تَحَاسَدُوا وَلاَ تَبَاغَضُوا وَلاَ تَجَسَّسُوا وَلاَ تَحَسَّسُوا وَلاَ تَنَاجَشُوا وَكُونُوا عِبَادَ اللَّهِ إِخْوَانًا " .
