Judgements For Cases Involving Bloodshed
Jami at-Tirmidhi
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 " .
'Abdullah narrated that the Messenger of Allah (ﷺ) said: "Indeed The First Cases To Be Judged Between The Worshippers Are Those Of Bloodshed."
