'A'isha reported: Allah's Messenger (may peace be upon him) said to me: I can well discern when you are pleased with me and when you are annoyed with me. I said: How do you discern it? Thereupon be said: When you are pleased with me you say;" No, by the Lord of Muhammad," and when you are annoyed with me, you say:" No, by the Lord of Ibrahim." I said: Allah's Messenger, by Allah, I in fact leave your name (when I am annoyed with you).
