حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ قَالَ بَيْنَمَا النَّاسُ بِقُبَاءٍ فِي صَلاَةِ الصُّبْحِ إِذْ جَاءَهُمْ آتٍ فَقَالَ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَدْ أُنْزِلَ عَلَيْهِ اللَّيْلَةَ قُرْآنٌ وَقَدْ أُمِرَ أَنْ يَسْتَقْبِلَ الْكَعْبَةَ فَاسْتَقْبِلُوهَا وَكَانَتْ وُجُوهُهُمْ إِلَى الشَّامِ فَاسْتَدَارُوا إِلَى الْكَعْبَةِ ‏.‏

Yahya related to me from Malik from Abdullah ibn Dinar that Abdullah ibn Umar said, "On one occasion when the people were praying subhat Quba a man came to them and said, 'A piece of Qur'an was sent down to the Messenger of Allah, may Allah bless him and grant him peace, last night, and he was ordered to face the Kaba, so face it.' They had been facing ash-Sham, so they turned round and faced the Kaba
