حَدَّثَنَا مُعَاذُ بْنُ فَضَالَةَ قَالَ حَدَّثَنَا هِشَامٌ عَنْ يَحْيَی عَنْ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ ثَوْبانَ قَالَ حَدَّثَنِي جَابِرُ بْنُ عَبْدِ اللَّهِ أَنَّ النَّبِيَّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ کَانَ يُصَلِّي عَلَی رَاحِلَتِهِ نَحْوَ الْمَشْرِقِ فَإِذَا أَرَادَ أَنْ يُصَلِّيَ الْمَکْتُوبَةَ نَزَلَ فَاسْتَقْبَلَ الْقِبْلَةَ
