The Messenger of Allah ﷺ passed Hamzah who was killed and disfigured. He said: If Safiyyah were not grieved, I would have left him until the birds and beasts of prey would have eaten him, and he would have been resurrected from their bellies. The garments were scanty and the slain were in great number. So one, two and three persons were shrouded in one garment. The narrator Qutaybah added: They were then buried in one grave. The Messenger of Allah ﷺ asked: Which of the two learnt the Qur'an more? He then advanced him toward the qiblah (direction of prayer). (Using translation from Abū Dāʾūd 3136)
أَنَّ رَسُولَ اللهِ ﷺ مَرَّ عَلَى حَمْزَةَ بَعْدَ أُحُدٍ وَقَدْ مُثِّلَ بِهِ فَقَالَ «لَوْلَا أَنْ تَجِدَ صَفِيَّةُ فِي نَفْسِهَا لَتَرَكْتُهُ حَتَّى تَأْكُلَهُ الْعَافِيَةُ حَتَّى يُحْشَرَ مِنْ بُطُونِهَا» ثُمَّ دَعَا بِنَمِرَةٍ فَكَانَتْ إِذَا مُدَّتْ عَلَى رَأْسِهِ بَدَتْ رِجْلَاهُ وَإِذَا مُدَّتَ عَلَى رِجْلَيْهِ الثِّيَابُ بَدَا رَأْسُهُ فَقَالَ رَسُولُ اللهِ ﷺ «مُدُّوهَا عَلَى رَأْسِهِ» وَقَلَّتِ الثِّيَابُ وَكَثُرَتِ الْقَتْلَى وَكَانَ الرَّجُلُ وَالرَّجُلَانِ وَالثَّلَاثَةُ يُكَفَّنُونَ فِي الثَّوْبِ الْوَاحِدِ وَكَانَ رَسُولُ اللهِ ﷺ يَسْأَلُ أَيُّهُمْ أَكْثَرُ قُرْآنًا فَيُقَدِّمُهُ إِلَى الْقِبْلَةِ فَدُفِنُوا وَلَمْ يُصَلِّ عَلَيْهِمْ
