Sunan Abi Dawud Book 2, Hadith 223
Alqamah and al-Aswad sought permission from Abdullah (ibn Mas'ud) for admission, and we remained sitting at his door for a long time. A slave-girl came out and gave them permission (to enter). He (Ibn Mas'ud) then got up and prayed (standing) between me (al-Aswad) and him (Alqamah). He then said: I witnessed the Messenger of Allah (ﷺ) doing similarly.
Get up, I shall lead you in prayer. Anas said: I got up and took a mat which had become black on account of long use. I then washed it with water. The Messenger of Allah (ﷺ) stood upon it. I and the orphan (Ibn Abi Dumairah, the freed slave of the prophet) stood in a row behind him. The old women stood behind us. He then led us in two raka'at of prayer and left.
Jabir ibn Yazid ibn al-Aswad reported on the authority of his father: I prayed behind the Messenger of Allah (ﷺ). When he finished the prayer, he would turn (his face from the direction of the Ka'bah).
