وَعَنْهُ قَالَ: «كَانَ اَلنَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَجْمَعُ بَيْنَ اَلرَّجُلَيْنِ مِنْ قَتْلَى أُحَدٍ فِي ثَوْبٍ وَاحِدٍ، ثُمَّ يَقُولُ: «أَيُّهُمْ أَكْثَرُ أَخْذًا لِلْقُرْآنِ?«, فَيُقَدِّمُهُ فِي اَللَّحْدِ، وَلَمْ يُغَسَّلُوا، وَلَمْ يُصَلِّ عَلَيْهِمْ»
The Messenger of Allah (sallallahu alayhi wa sallam) had each two martyrs of the battle of Uhud wrapped in one shroud, and then would ask, “Which one of them knew more of the Qur’An?” He would put that one (that was pointed out) first in the grave. They were not washed and the Messenger of Allah (sallallahu alayhi wa sallam) did not offer a funeral prayer for them. Related by Al-Bukhari.
