Abū Sufyān ibn al-Ḥārith ibn ‘Abd al-Muṭṭalib (Arabic: أبو سفيان بن الحارث بن عبد المطلب), born al-Mughīrah (المغيرة), was a companion and first cousin of the Islamic prophet Muhammad.
He was the son of Al-Harith ibn Abdulmuttalib. He was wet-nursed for a few days by Halimah bint Abi Dhuayb, making him a foster-brother of Muhammad.
He married his cousin, Jumanah bint Abi Talib, and they had a son, Ja'far. He also married another cousin, Umm 'Amr bint al-Muqawwim, and they had a daughter, Atika. This may be the same daughter who later married Abu Sufyan's nephew Abdul-Muttalib (son of Rabi'ah ibn al-Harith).
In their youth, Abu Sufyan and Muhammad were close friends; but as soon as Muhammad declared himself a prophet in 610, Abu Sufyan “treated him with enmity as no one before him." As he later explained it: "We were with a community, a people of high-mindedness. I saw the excellence of the people who lived with their discernment and opinion. They went through a mountain pass, and we followed. Then the people of nobility and age began to break away from Muhammad, and they helped their gods and defended their forefathers, and we followed them."
"He showed hatred toward the Prophet for twenty years, never remaining behind when the Quraysh set out to fight Muhammad." He fought at the Battle of Badr on the side of the polytheists. He was one of the first to arrive back in Mecca with the news of their defeat. As he told his uncle, Abu Lahab: "As soon as we met the party we turned our backs and they were killing and capturing us just as they pleased; and by God I don't blame the people for that. We met men in white on piebald horses between heaven and earth, and, by Allah, they spared nothing, and none could withstand them."
He also wrote satirical poems against Muhammad and the Muslims and insulted Hassan ibn Thabit:
