While some people were at Quba (offering) morning prayer, a man came to them and said, "Last night Qur'anic Verses have been revealed whereby the Prophet (ﷺ) has been ordered to face the Ka`ba (at Mecca), so you too should face it." So they, keeping their postures, turned towards the Ka`ba. Formerly the people were facing Sham (Jerusalem) (Allah said):-- "And from whence-so-ever you start forth (for prayers), turn your face in the direction of the Sacred Mosque of Mecca (Al-Masjid-ul-Haram), and whence-so-ever you are, turn your face towards it (when you pray)" (2.150)
Sahih al-Bukhari Book 65, Hadith 20
← Previous Hadith We prayed along with the Prophet (ﷺ) facing Jerusalem for sixteen or seventeen months. Then Allah ordered him to turn his face towards the Qibla (in Mecca):-- "And from whence-so-ever you start forth (for prayers) turn your face in the direction of (the Sacred Mosque of Mecca) Al-Masjid-ul Haram.." (2.149)

Sahih al-Bukhari Book 65, Hadith 19 Next Hadith → While some people were offering Fajr prayer at Quba mosque, someone came to them and said, "Qur'anic literature" has been revealed to Allah's Messenger (ﷺ) tonight, and he has been ordered to face the Ka`ba (of Mecca) so you too, should turn your faces towards it. Their faces were then towards Sham (Jerusalem), so they turned towards the Qibla (i.e. Ka`ba of Mecca).
