Musnad Abu Ya'la al-Mawsili 79:2

Muhammad ibn 'Abbad al-Makki narrated to us, Abu Sa'id, the freed slave of Banu Hashim, narrated to us, from Abu Khalaf, from 'Abdullah ibn 'Awf, who said: I heard Abu Jum'ah Junbadh ibn Sab' saying: "I fought the Prophet, may Allah bless him and grant him peace, at the beginning of the day as a disbeliever, and I fought alongside him at the end of the day as a Muslim. We were three men and seven women, and concerning us was revealed: 'And had it not been for believing men and believing women...' [Surah al-Fath, 48:25]."
