It is narrated from Hazrat Aisha (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) used to say to me, "When you are angry with me, I come to know of your anger, and when you are pleased, I come to know of that as well." I asked, "O Messenger of Allah! How do you come to know of this?" The Prophet (peace and blessings be upon him) said, "When you are angry, you say 'No, by the Lord of Muhammad,' and when you are pleased, you say 'No, by the Lord of Ibrahim (peace be upon him).'" I said, "You speak the truth, but by Allah, I only leave out your name (there is nothing in my heart)."
