Jami at-Tirmidhi · Book 16: The Book on Blood Money · Judgements For Cases Involving Bloodshed
'Abdullah narrated that the Messenger of Allah (ﷺ) said:
حَدَّثَنَا أَبُو كُرَيْبٍ ، حَدَّثَنَا وَكِيعٌ ، عَنِ الأَعْمَشِ ، عَنْ أَبِي وَائِلٍ ، عَنْ عَبْدِ اللَّهِ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ أَوَّلَ مَا يُقْضَى بَيْنَ الْعِبَادِ فِي الدِّمَاءِ " .
"Indeed the first cases to be judged between the worshippers are those of bloodshed."
