Hadith
حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَنْبَأَنَا هِشَامٌ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ يَعِيشَ بْنِ الْوَلِيدِ بْنِ هِشَامٍ، وَأَبُو مُعَاوِيَةَ شَيْبَانُ عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ يَعِيشَ بْنِ الْوَلِيدِ بْنِ هِشَامٍ، عَنِ الزُّبَيْرِ بْنِ الْعَوَّامِ، رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ دَبَّ إِلَيْكُمْ دَاءُ الْأُمَمِ قَبْلَكُمْ الْحَسَدُ وَالْبَغْضَاءُ وَالْبَغْضَاءُ هِيَ الْحَالِقَةُ حَالِقَةُ الدِّينِ لَا حَالِقَةُ الشَّعَرِ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَا تُؤْمِنُوا حَتَّى تَحَابُّوا أَفَلَا أُنَبِّئُكُمْ بِشَيْءٍ إِذَا فَعَلْتُمُوهُ تَحَابَبْتُمْ أَفْشُوا السَّلَامَ بَيْنَكُمْ.
Narrated by It was narrated that az-Zubair bin al-`Awwam (رضي الله عنه) said:
The Messenger of Allah (ﷺ) said: “There has come to you the disease of the nations before you, jealousy and hatred. Hatred is the `shaver` (destroyer) that shaves (destroys) religious commitment; it does not shave hair. By the One in Whose Hand is the soul of Muhammad, you will not believe until you love one another. Shall I not tell you something which, if you do it, you will love one another? Spread (the greeting of) salam amongst yourselves.”
