Al-Bara' b. 'Azib reported
I said prayer with the Apostle (ﷺ) turning towards Bait-ul-Maqdis for sixteen months till this verse of Surah Baqara wis revealed:" And wherever you are turn your faces towards it" (ii. 144). This verse was revealed when the Apostle (ﷺ) had said prayer. A person amongst his people passed by the people of Ansar as they were engaged in prayer. He narrated to them (this command of Allah) and they turned their faces towards the Ka'ba.
Abu Ishaq reported
I heard al-Bara' saying: We prayed with the Messenger of Allah (ﷺ) (with our faces) towards Bait-ul-Maqdis for sixteen months or seventeen months. Then we were made to change (our direction) towards the Ka'ba.
Ibn 'Umar reported
As the people were praying at Quba' a man came to them and said: It has been revealed to file Messenger of Allah (ﷺ) during the night and he has been directed to turn towards the Ka'ba. So turn towards it. Their faces were towards Syria and they turned round towards Ka'ba.
Ibn 'Umar reported
As the people were engaged in the morning prayer a man came to them. The rest of the hadith is the same.
Anas reported
The Messenger of Allah (ﷺ) used to pray towards Bait-ul-Maqdis, that it was revealed (to him):" Indeed We see the turning of the face to heaven, wherefore We shall assuredly cause thee to turn towards Qibla which shall please thee. So turn thy face towards the sacred Mosque (Ka'ba)" (ii. 144). A person from Banu Salama was going; (he found the people) in ruk'u (while) praying the dawn prayer and they had said one rak'ah. He said in a loud voice: Listen! the Qibla has been changed and they turned towards (the new) Qibla (Ka'ba) in that very state.
