Sahih Muslim Book 45, Hadith 124
O, it is you; you have grown young. May you not advance in years! That slave-girl returned to Umm Sulaim weeping. Umm Sulaim said: O daughter, what is the matter with you? She said: Allah's Apostle (ﷺ) has invoked curse upon me that I should not grow in age and thus I would never grow in age, or she said, in my (length) of life. Umm Sulaim went out wrapping her head-dress hurriedly until she met Allah's Messenger (ﷺ). He said to her: Umm Sulaim, what is the matter with you? She said: Allah's Apostle, you invoked curse upon my orphan girl. He said: Umm Sulaim, what is that? She said: She (the orphan girl) states you have cursed her saying that she might not grow in age or grow in life. Allah's Messenger (ﷺ) smiled and then said: Umm Sulaim, don't you know that I have made this term with my Lord. And the term with my Lord is that I said to Him: 1 am a human being and I am pleased just as a human being is pleased and I lose temper just as a human being loses temper, so for any person from amongst my Ummah whom I curse and he in no way deserves it, let that, O Lord, be made a source of purification and purity and nearness to (Allah) on the Day of Resurrection.
I am a human being and I have made this term with my Lord, the Exalted and Glorious: For any servant amongst Muslims whom I curse or scold, make that a source of purity and reward. This hadith has been narrated on the authority of Ibn Juraij with the same chain of transmitters.
I was playing with children that Allah's Messenger (ﷺ) happened to pass by (us). I hid myself behind the door. He (the Prophet) came and patted my shoulders and said: Go and call Mu'awiya. I returned and said: He is busy in taking food. He again asked me to go and call Mu'awiya to him. I went (and came back) and said that he was busy in taking food, whereupon he said: May Allah not fill his belly! Ibn Muthanna, said: I asked Umm Umayya what he meant by the word Hatani. He said: It means "he patted my shoulders."
