Musnad Ahmad 1153:1692

Waki’ and Muhammad ibn Ja’far narrated to us, they said: Shu’bah narrated to us, from al-Hakam, from Ibrahim, from al-Aswad, who said: I said to ‘Aishah: "What would the Prophet, peace and blessings of Allah be upon him, do when he entered his house?" She said: "He would be in the service of his family, and when the prayer time arrived, he would go out and pray."
