Musnad Ahmad 1313:5

Zakariya ibn 'Adi narrated to us, he said: Ibn al-Mubarak informed us, from Yunus, from al-Zuhri, from Sa'id ibn al-Musayyib, from Safwan ibn Umayyah, who said: "The Messenger of Allah (peace and blessings of Allah be upon him) gave to me on the day of Hunayn, and he was the most hateful of people to me. He continued to give to me until he became the most beloved of people to me."
