Compiled by Imam Abu Dawud as-Sijistani
حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ، حَدَّثَنَا ابْنُ أَبِي فُدَيْكٍ، أَخْبَرَنِي عَمْرُو بْنُ عُثْمَانَ بْنِ هَانِئٍ، عَنِ الْقَاسِمِ، قَالَ دَخَلْتُ عَلَى عَائِشَةَ فَقُلْتُ يَا أُمَّهْ اكْشِفِي لِي عَنْ قَبْرِ النَّبِيِّ صلى الله عليه وسلم وَصَاحِبَيْهِ رضى الله عنهما فَكَشَفَتْ لِي عَنْ ثَلاَثَةِ قُبُورٍ لاَ مُشْرِفَةٍ وَلاَ لاَطِئَةٍ مَبْطُوحَةٍ بِبَطْحَاءِ الْعَرْصَةِ الْحَمْرَاءِ قَالَ أَبُو عَلِيٍّ يُقَالُ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم مُقَدَّمٌ وَأَبُو بَكْرٍ عِنْدَ رَأْسِهِ وَعُمَرُ عِنْدَ رِجْلَىْ رَسُولِ اللَّهِ صلى الله عليه وسلم .
I said to Aisha! Mother, show me the grave of the Messenger of Allah (ﷺ) and his two Companions (Allah be pleased with them). She showed me three graves which were neither high nor low, but were spread with soft red pebbles in an open space. Abu 'Ali said: It is said that the Messenger of Allah (ﷺ) is forward, Abu Bakr is near his head and 'Umar is near is feet. His head is at the feet of the Messenger of Allah (ﷺ).
