Sa'id bin Jubayr سعيد بن جبير الأسدي · The Book of Salah

"The Messenger of Allah (ﷺ) delayed 'Isha' until 'Umar called him and said: 'The women and children have gone to sleep.' Then the Messenger of Allah (ﷺ) came out and said: 'There is no one who is offering this prayer but you.' And at that time no one used to pray except the people of Al-Madinah."

"The Messenger of Allah (ﷺ) came to Al-Madinah and prayed toward Bait Al-Maqdis for sixteen months, then he was commanded to face towards the Ka'bah. A man who had prayed with the Prophet (ﷺ) passed by some of the Ansar and said: 'I bear witness that the Messenger of Allah (ﷺ) has been commanded to face towards the Ka'bah' so they turned to face the Ka'bah."
