Sakhr ibn Harb ibn Umayya ibn Abd Shams (Arabic: صخر بن حرب بن أمية بن عبد شمس, romanized: Ṣakhr ibn Ḥarb ibn Umayya ibn ʿAbd Shams; c. 565 — c. 653), better known by his kunya Abu Sufyan (Arabic: أبو سفيان, romanized: Abū Sufyān), 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 and member of the Quraysh, commanding the Meccans at the battles of Uhud and the Trench in 625 and 627.
No one was forced to convert to Islam. Abu Sufyan and his son Mo'awiyah and Khalid ibn al-Waleed and others from Quraish saw the victory of Islam, and became sure that there will be no future but under the banner of Islam, they wanted to secure a political and social future for them, by declaring themselves as Muslims. The Prophet never punished them on their long history of fighting against Islam, but told them: Go away, you are been freed اذهبوا فأنتم الطلقاء.
