An-Nu’man (RA) said, when he was delivering a Khutbah: “My father took me to the Messenger of Allah (peace be upon him) to ask him to bear witness to a gift that he had given me. He said: ‘Do you have any other children besides him?’ He said: ‘Yes.’ He said: ‘Treat them equally.'”
Sunan an-Nasa’i, Book 31, Hadith 15
