Mishkat al-Masabih 16 Retaliation كتاب القصاص 15

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

‘Abdallah b. ‘Amr reported the Prophet as saying, “The passing away of the world would mean less to God than the murder of a Muslim man.” Tirmidhi and Nasa’i transmitted it. Some traced it only to the Companion, and that is the soundest view. Ibn Majah transmitted it on the authority of al-Bara’ b. ‘Azib.
