Sahih al-Bukhari 1343Book 23, Hadith 98
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، حَدَّثَنَا اللَّيْثُ، قَالَ حَدَّثَنِي ابْنُ شِهَابٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ كَعْبِ بْنِ مَالِكٍ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم 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 يَوْمَ الْقِيَامَةِ ". وَأَمَرَ بِدَفْنِهِمْ فِي دِمَائِهِمْ، وَلَمْ يُغَسَّلُوا وَلَمْ يُصَلَّ عَلَيْهِمْ.
The Prophet (ﷺ) collected every two martyrs of Uhud in one piece of cloth, then he would ask, "Which of them had (knew) more of the Qur'an?" When one of them was pointed out for him, he would put that one first in the grave and say, "I will be a witness on these on the Day of Resurrection." He ordered them to be buried with their blood on their bodies and they were neither washed nor was a funeral prayer offered for them.
