Hadith 994B1

وَحَدَّثَنِي، عَنْ مَالِك، أَنَّهُ بَلَغَهُ، عَنْ أَهْلِ الْعِلْمِ أَنَّهُمْ كَانُوا يَقُولُونَ : الشُّهَدَاءُ فِي سَبِيلِ اللَّهِ لَا يُغَسَّلُونَ، وَلَا يُصَلَّى عَلَى أَحَدٍ مِنْهُمْ، وَإِنَّهُمْ يُدْفَنُونَ فِي الثِّيَابِ الَّتِي قُتِلُوا فِيهَا .
Imam Malik, may Allah have mercy on him, received from the people of knowledge that they used to say: The martyrs should neither be given a bath nor should funeral prayer be offered over them, rather they should be buried in the very clothes in which they were martyred.
