The Messenger of Allah ﷺ commanded to remove weapons and skins from the martyrs of Uhud, and that they should be buried with their blood and clothes. (Using translation from Abū Dāʾūd 3134)
أَمَرَ رَسُولُ اللهِ ﷺ يَوْمَ أُحُدٍ بِالشُّهَدَاءِ أَنْ يُنْزَعَ عَنْهُمِ الْحَدِيدُ وَالْجُلُودُ وَقَالَ ادْفِنُوهُمْ بِدِمَائِهِمْ وَثِيَابِهِمْ
