Expedition of Ubaydah ibn al-Harith

In April 623, the Islamic prophet Muhammad sent Ubaydah ibn al-Harith with a party of sixty armed Muhajirun (Muslim migrants to Medina) to the valley of Rabigh, in modern-day Saudi Arabia. They expected to intercept a Quraysh caravan that was returning from Syria under the protection of Abu Sufyan ibn Harb and 200 armed riders.^{[1][2][3][4][5]} The Muslim party travelled as far as the wells at Thanyat al-Murra,^[1][4] where Sa`d ibn Abi Waqqas shot an arrow at the Quraysh. This is known as the first arrow of Islam.^[6][7] Despite this surprise attack, "they did not unsheathe a sword or approach one another," and the Muslims returned empty-handed;^[2][3][4] however, two Meccans traders left their caravan, became Muslim, and went with the expedition back to Medina.^[8]
