Musnad Ahmad 1313:0

Safwan ibn Umayyah reported: The Messenger of Allah, peace and blessings be upon him, gave me on the day of Hunayn while he was the most hateful of people to me, and he continued to give me until he became the most beloved of people to me. He said: He gave me and he gave me, and he gave me, until he became the most beloved of people to me.
