Yazid ibn Abi Sufyan in the context of "Abu Sufyan ibn Harb"

Sakhr ibn Harb ibn Umayya (Arabic: صَخْرِ ٱبْن حَرْب ٱبْن أُمَيَّةَ, romanized: Ṣakhr ibn Ḥarb ibn Umayya; c. 560—653), commonly known by his kunya Abu Sufyan (Arabic: أَبُو سُفْيَانُ, romanized: Abū Sufyān), was a prominent opponent-turned companion and father-in-law of the Islamic prophet Muhammad. He was the father of the first Umayyad caliph Mu'awiya I (r. 661–680) and namesake of the Sufyanid line of Umayyad caliphs which ruled from 661 to 684.

Abu Sufyan was a leader and merchant from the Quraysh tribe of Mecca. During his early career, he often led trade caravans to Syria. He had been among the main leaders of Meccan opposition to Muhammad, the prophet of Islam, commanding the Meccans at the battles of the Uhud and Trench in 625 and 627 CE. However, when Muhammad entered Mecca in 630, he was among the first to submit and was given a stake in the nascent Muslim state, playing a role at the Battle of Hunayn and the subsequent destruction of the polytheistic sanctuary of al-Lat in Ta'if. After Muhammad's death, he may have been appointed as the governor of Najran by Caliph Abu Bakr (r. 632–634) for an unspecified period. Abu Sufyan later played a supporting role in the Muslim army at the Battle of the Yarmuk against the Byzantines in Syria. His sons Yazid and later Mu'awiya were given command roles in that province and the latter went on to establish the Umayyad Caliphate in 661.
