Sayyiduna Safwan bin Umayyah (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) gave me (wealth) on the day of Hunayn, while at that time he (peace and blessings be upon him) was the most hateful of all people to me. He (peace and blessings be upon him) kept on giving to me until he (peace and blessings be upon him) became the most beloved of all people to me.
