Narrated Jabir:

The Prophet (ﷺ) said, "Bury them (i.e. martyrs) with their blood." (that was) On the day of the Battle of Uhud. He did not get them washed.

حَدَّثَنَا أَبُو الْوَلِيدِ، حَدَّثَنَا لَيْثٌ، عَنِ ابْنِ شِهَابٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ كَعْبٍ، عَنْ جَابِرٍ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏

‏ ادْفِنُوهُمْ فِي دِمَائِهِمْ ‏

‏‏.‏ ـ يَعْنِي يَوْمَ أُحُدٍ ـ وَلَمْ يُغَسِّلْهُمْ‏.‏

Martyrdom for the sake of Allah has a great standing in Islam. The martyr has several merits; and martyrs who have died in battle have some special legal rulings. In this hadeeth, some of them are explained, as Jaabir ibn ʿAbdullah (may Allah be pleased with both of them) reports that the Prophet ﷺ ordered that the martyrs be buried in their garments with their blood [on them] and did not wash them; in order to preserve the sign of martyrdom on them. The traces of the battle and the blood that occurred therein remained on them. This happened in the Battle of Uhud - which is one of the well-known mountains of al-Madeenah - and that battle happened during the month of Shawwaal in the third year after Hijrah. It can be inferred from this hadeeth that the martyr is not washed, and that their blood is pure while it remains on them; because if it was considered impure, heﷺwould have ordered that it be removed from the body of the dead before burying them. .
