Hadith 2
The Book of Fighting [The Prohibition of Bloodshed]
It was narrated that 'Abdullah bin 'Amr bin Al-'As said:
"The Messenger of Allah [ﷺ] said: 'By the One in Whose Hand is my soul, killing a believer is more grievous before Allah than the extinction of the whole world.'"
أَخْبَرَنَا مُحَمَّدُ بْنُ مُعَاوِيَةَ بْنِ مَالَجَ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ سَلَمَةَ الْحَرَّانِيُّ، عَنِ ابْنِ إِسْحَاقَ، عَنْ إِبْرَاهِيمَ بْنِ مُهَاجِرٍ، عَنْ إِسْمَاعِيلَ، مَوْلَى عَبْدِ اللَّهِ بْنِ عَمْرٍو عَنْ عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم
وَالَّذِي نَفْسِي بِيَدِهِ لَقَتْلُ مُؤْمِنٍ أَعْظَمُ عِنْدَ اللَّهِ مِنْ زَوَالِ الدُّنْيَا
