Musnad Ahmad 1153:1761

Waki’ narrated to us, from Hisham, from his father, from Aisha, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said to me: "I certainly know when you are angry and when you are pleased." I said: "How do you know that?" He said: "When you are angry, you say: 'No, by the Lord of Ibrahim.' And when you are pleased, you say: 'No, by the Lord of Muhammad.'"
