"I heard my father say: I heard Anas say: 'One of the companions of the Prophet ﷺ told me that on the Night Journey, the Prophet ﷺ passed by Musa, peace be upon him, and he was praying in his grave.'" (Using translation from Nasāʾī 1636)
حَدَّثَنِي بَعْضُ أَصْحَابِ النَّبِيِّ ﷺ أَنَّ النَّبِيَّ ﷺ لَيْلَةَ أُسْرِيَ بِهِ «مَرَّ عَلَى مُوسَى وَهُوَ يُصَلِّي فِي قَبْرِهِ»
