أَخْبَرَنِي أَحْمَدُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا حَبَّانُ، قَالَ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، قَالَ أَنْبَأَنَا ثَابِتٌ، وَسُلَيْمَانُ التَّيْمِيُّ، عَنْ أَنَسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " مَرَرْتُ عَلَى قَبْرِ مُوسَى عَلَيْهِ السَّلاَمُ وَهُوَ يُصَلِّي فِي قَبْرِهِ " .
It was narrated from Anas that: The Prophet (ﷺ) said: "I passed by the grave of Musa, peace be upon him, and he was praying in his grave."
