Sahih Bukhari Volume 2, Book 23, Hadith 1348

حَدَّثَنَا ابْنُ مُقَاتِلٍ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا لَيْثُ بْنُ سَعْدٍ، حَدَّثَنِي ابْنُ شِهَابٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ كَعْبِ بْنِ مَالِكٍ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ 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 أَحَدِهِمَا قَدَّمَهُ فِي اللَّحْدِ وَقَالَ ‏"‏ أَنَا شَهِيدٌ عَلَى هَؤُلاَءِ ‏"‏‏.‏ وَأَمَرَ بِدَفْنِهِمْ بِدِمَائِهِمْ، وَلَمْ يُصَلِّ عَلَيْهِمْ وَلَمْ يُغَسِّلْهُمْ‏.

Narrated Jabir bin Abdullah(R.A.): Allah's Messenger(s.a.w.) shrouded every two men from amongst the martyrs of Uhud in one piece of cloth, and then he would ask,"Which of them had(knew) more of the Quran?"And if one of them was pointed out for him(as having more knowledge of it), he would put that one first in the grave and say,"I will be a witness on these(on the Day of Resyrrection)."Then he ordered them to be burried with blood on their bodies.Neither he offered their funeral prayer nor he gave them Ghusl(bath).
