(1) بَابُ مَا جَاءَ فِي إِجَازَةِ خَبَرِ الْوَاحِدِ الصَّدُوقِ فِي الأَذَانِ وَالصَّلاَةِ وَالصَّوْمِ وَالْفَرَائِضِ وَالأَحْكَامِ
Narrated `Abdullah bin `Umar:
While the people were at Quba offering the morning prayer, suddenly a person came to them saying, "Tonight Divine Inspiration has been revealed to Allah's Messenger (ﷺ) and he has been ordered to face the Ka`ba (in prayers): therefore you people should face it." There faces were towards Sham, so they turned their faces towards the Ka`ba (at Mecca). (DE)
