Muwatta Malik, Book 21, Hadith 1010 (In-Book) ⓘ

Yahya related to me from Malik from Abd ar-Rahman ibn Abi Sasaca that he had heard that Amr ibn al-Jamuh al-Ansari and Abdullah ibn Umar al-Ansari, both of the tribe of Banu Salami, had their grave uncovered by a flood. Their grave was part of what was left after the flood. They were in the same grave, and they were among those martyred at Uhud. They were dug up so that they might be moved. They were found unchanged. It was as if they had died only the day before. One of them had been wounded, and he had put his hand over his wound and had been buried like that. His hand was pulled away from his wound and released, and it returned to where it had been. It was forty-six years between Uhud and the day they were dug up. Malik said, "There is no harm in burying two or three men in the same grave due to necessity. The oldest one is put next to the qibla."

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي صَعْصَعَةَ، أَنَّهُ بَلَغَهُ أَنَّ عَمْرَو بْنَ الْجَمُوحِ، وَعَبْدَ اللَّهِ بْنَ عَمْرٍو الأَنْصَارِيَّيْنِ، ثُمَّ السَّلَمِيَّيْنِ كَانَا قَدْ حَفَرَ السَّيْلُ قَبْرَهُمَا وَكَانَ قَبْرُهُمَا مِمَّا يَلِي السَّيْلَ وَكَانَا فِي قَبْرٍ وَاحِدٍ وَهُمَا مِمَّنِ اسْتُشْهِدَ يَوْمَ أُحُدٍ فَحُفِرَ عَنْهُمَا لِيُغَيَّرَا مِنْ مَكَانِهِمَا فَوُجِدَا لَمْ يَتَغَيَّرَا كَأَنَّهُمَا مَاتَا بِالأَمْسِ وَكَانَ أَحَدُهُمَا قَدْ جُرِحَ فَوَضَعَ يَدَهُ عَلَى جُرْحِهِ فَدُفِنَ وَهُوَ كَذَلِكَ فَأُمِيطَتْ يَدُهُ عَنْ جُرْحِهِ ثُمَّ أُرْسِلَتْ فَرَجَعَتْ كَمَا كَانَتْ وَكَانَ بَيْنَ أُحُدٍ وَبَيْنَ يَوْمَ حُفِرَ عَنْهُمَا سِتٌّ وَأَرْبَعُونَ سَنَةً ‏.‏ قَالَ مَالِكٌ لاَ بَأْسَ أَنْ يُدْفَنَ الرَّجُلاَنِ وَالثَّلاَثَةُ فِي قَبْرٍ وَاحِدٍ مِنْ ضَرُورَةٍ وَيُجْعَلَ الأَكْبَرُ مِمَّا يَلِي الْقِبْلَةَ ‏.‏
