Sahih Bukhari | Volume 7 | Hadith Number 155
Narrated by 'Aisha
That Allah's Apostle said to her, "I you are pleased with me or angry with me." I said, "Whence do you know that?" He said, "When you are pleased with me, you say, 'No, by the Lord of Muhammad,' but when you are angry with me, then you say, 'No, by the Lord of Abraham.' " Thereupon I said, "Yes (you are right), but by Allah, O Allah's Apostle, I leave nothing but your name."
