Sahih Bukhari
Hadith #399
Narrated Bara' bin `Azib:Allah's Messenger (ﷺ) prayed facing Baitul-Maqdis for sixteen or seventeen months but he loved to face the Ka`ba (at Mecca) so Allah revealed: ""Verily, We have seen the turning of your face to the heaven!"" (2:144) So the Prophet (ﷺ) faced the Ka`ba and the fools amongst the people namely ""the Jews"" said, ""What has turned them from their Qibla (Baitul-Maqdis) which they formerly observed"""" (Allah revealed): ""Say: 'To Allah belongs the East and the West. He guides whom He wills to a straight path'."" (2:142) A man prayed with the Prophet (facing the Ka`ba) and went out. He saw some of the Ansar praying the `Asr prayer with their faces towards Baitul-Maqdis, he said, ""I bear witness that I prayed with Allah's Messenger (ﷺ) facing the Ka`ba."" So all the people turned their faces towards the Ka`ba
