Sahih Bukhari Volume 5, Book 64, Hadith 4081

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ كَعْبِ بْنِ مَالِكٍ، أَنَّ جَابِرَ بْنَ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَجْمَعُ بَيْنَ الرَّجُلَيْنِ مِنْ قَتْلَى أُحُدٍ فِي ثَوْبٍ وَاحِدٍ ثُمَّ يَقُولُ ‏"‏ أَيُّهُمْ أَكْثَرُ أَخْذًا لِلْقُرْآنِ ‏"‏‏.‏ فَإِذَا أُشِيرَ لَهُ إِلَى أَحَدٍ، قَدَّمَهُ فِي اللَّحْدِ، وَقَالَ ‏"‏ أَنَا شَهِيدٌ عَلَى هَؤُلاَءِ يَوْمَ الْقِيَامَةِ ‏"‏‏.‏ وَأَمَرَ بِدَفْنِهِمْ بِدِمَائِهِمْ، وَلَمْ يُصَلِّ عَلَيْهِمْ، وَلَمْ يُغَسَّلُوا‏.

Narrated By Jabir bin 'Abdullah : Allah's Apostle used to shroud two martyrs of Uhud in one sheet and then say, "Which of them knew Qur'an more?" When one of the two was pointed out, he would put him first in the grave. Then he said, "I will be a witness for them on the Day of Resurrection." He ordered them to be buried with their blood (on their bodies). Neither was the funeral prayer offered for them, nor were they washed.
