Musnad Ahmad 1173:13

'Affan narrated to us, he said: Hammad ibn Salamah narrated to us, he said: Abu Husayn narrated to us, he said: There was a day for the people of Medina in which they would play. So I entered upon al-Rubayyi' bint Mu'awwidh ibn 'Afra', and she said: The Messenger of Allah, peace and blessings of Allah be upon him, entered upon me and sat on this place of my bedding, and I had two young girls with me lamenting my forefathers who were killed on the day of Badr, beating on tambourines—and 'Affan said once: on a tambourine. They said in what they were saying: "And among us is a Prophet who knows what will be tomorrow." He said: "As for this, do not say it."
