Sunan Ibn Majah, Hadith 1515 ⓘ
It was narrated from Ibn ‘Abbas that the Messenger of Allah commanded that the weapons and armor should be removed from the slain of Uhud, and they should be buried in their clothes stained with blood.
حَدَّثَنَا مُحَمَّدُ بْنُ زِيَادٍ، حَدَّثَنَا عَلِيُّ بْنُ عَاصِمٍ، عَنْ عَطَاءِ بْنِ السَّائِبِ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ أَمَرَ بِقَتْلَى أُحُدٍ أَنْ يُنْزَعَ عَنْهُمُ الْحَدِيدُ وَالْجُلُودُ وَأَنْ يُدْفَنُوا فِي ثِيَابِهِمْ بِدِمَائِهِمْ .
