The Book of Virtue, Good Manners and Joining of the Ties of Relationship (Kitab Al-Birr was-Salat-I-wa'l-Adab)
Muslim :: Book 32 : Hadith 6298
Ibn Abbas reported: I was playing with children that Allah's Messenger (may peace be upon him) happened to pass by (us). I hid myself behind the door. He (the Holy Prophet) came and he patted upon 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'swiya 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".
