وَحَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ عُمَرَ الْقَوَارِيرِيُّ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ عَبْدِ الْمَلِكِ بْنِ أَبِي سُلَيْمَانَ، قَالَ حَدَّثَنَا سَعِيدُ بْنُ جُبَيْرٍ، عَنِ ابْنِ عُمَرَ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي وَهُوَ مُقْبِلٌ مِنْ مَكَّةَ إِلَى الْمَدِينَةِ عَلَى رَاحِلَتِهِ حَيْثُ كَانَ وَجْهُهُ - قَالَ - وَفِيهِ نَزَلَتْ ‏{‏ فَأَيْنَمَا تُوَلُّوا فَثَمَّ وَجْهُ اللَّهِ‏}‏
