حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ سُفْيَانَ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ بَيْنَا النَّاسُ يُصَلُّونَ الصُّبْحَ فِي مَسْجِدِ قُبَاءٍ إِذْ جَاءَ جَاءٍ فَقَالَ أَنْزَلَ اللَّهُ عَلَى النَّبِيِّ صلى الله عليه وسلم قُرْآنًا أَنْ يَسْتَقْبِلَ الْكَعْبَةَ فَاسْتَقْبِلُوهَا. فَتَوَجَّهُوا إِلَى الْكَعْبَةِ.
