Silsilat al-Ahadith al-Sahihah

Lady Aisha (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) said: "I recognize your anger and your pleasure." She said: I asked, "O Messenger of Allah! How do you recognize it?" He (peace and blessings be upon him) said: "When you are pleased, you say, 'By the Lord of Muhammad!' and when you are angry, you say, 'By the Lord of Ibrahim!'" Lady Aisha (may Allah be pleased with her) said: I replied, "Yes, (but) I only leave out your name (there is no anger in my heart)."
