عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «لَزَوَالُ الدُّنْيَا أَهْوَنُ عَلَى اللَّهِ مِنْ قَتْلِ رَجُلٍ مُسْلِمٍ» . رَوَاهُ التِّرْمِذِيّ وَالنَّسَائِيّ ووقفَه بعضُهم وَهُوَ الْأَصَح وَرَوَاهُ ابْنُ مَاجَهْ عَنِ الْبَرَاءِ بْنِ عَازِبٍ

Abu Sa'id and Abu Huraira reported God's Messenger as saying, “If the inhabitants of heaven and earth were to share in [shedding] the blood of a believer, God would overturn them in hell.” Tirmidhi transmitted it, saying this is a gharib tradition.
