أَخْبَرَنَا مُحَمَّدُ بْنُ عَلِيِّ بْنِ حَرْبٍ، قَالَ حَدَّثَنَا مُعَاذُ بْنُ خَالِدٍ، قَالَ أَنْبَأَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ سُلَيْمَانَ التَّيْمِيِّ، عَنْ ثَابِتٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ أَتَيْتُ لَيْلَةَ أُسْرِيَ بِي عَلَى مُوسَى عَلَيْهِ السَّلاَمُ عِنْدَ الْكَثِيبِ الأَحْمَرِ وَهُوَ قَائِمٌ يُصَلِّي فِي قَبْرِهِ .
It was narrated from Anas bin Malik that: The Messenger of Allah (ﷺ) said: "On the night on which I was taken on the Night Journey (Al-Isra') I came to Musa, peace be upon him, at the red dune, and he was standing, praying in his grave."
