'Ali said to me: I am sending you on the same mission as the Messenger of Allah ﷺ sent me that I should not leave a high grave without leveling it and an image without obliterating it.  

لِي أَبْعَثُكَ عَلَى مَا بَعَثَنِي عَلَيْهِ رَسُولُ اللَّهِ ﷺ أَنْ لاَ أَدَعَ قَبْرًا مُشْرِفًا إِلاَّ سَوَّيْتُهُ وَلاَ تِمْثَالاً إِلاَّ طَمَسْتُهُ  

We were with Fudalah b. 'Ubaid at Rudis in the land of Rome. One of our Companions dies, Fudalah commanded us to dig his grave; it was (dug and) levelled. He then said: I heard the Messenger of Allah ﷺ commanding to level them. Abu Dawud said: Rudis is an island, in the sea.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَأْمُرُ بِتَسْوِيَتِهَا  

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.  

دَخَلْتُ عَلَى عَائِشَةَ فَقُلْتُ يَا أُمَّهْ اكْشِفِي لِي عَنْ قَبْرِ النَّبِيِّ ﷺ وَصَاحِبَيْهِ ؓ فَكَشَفَتْ لِي عَنْ ثَلاَثَةِ قُبُورٍ لاَ مُشْرِفَةٍ وَلاَ لاَطِئَةٍ مَبْطُوحَةٍ بِبَطْحَاءِ الْعَرْصَةِ الْحَمْرَاءِ قَالَ أَبُو عَلِيٍّ يُقَالُ إِنَّ رَسُولَ اللَّهِ ﷺ مُقَدَّمٌ وَأَبُو بَكْرٍ عِنْدَ رَأْسِهِ وَعُمَرُ عِنْدَ رِجْلَىْ رَسُولِ اللَّهِ ﷺ
