Muhajirun

Muhajirun (Arabic: المهاجرون‎ The Emigrants) were the early, initial Muslims who followed the Islamic prophet Muhammad on his Hijra (withdrawal from Mecca to Medina). The early Muslims from Medina are called the Ansar ("helpers").

During Muhammad's era

About a month after Hamzah's unsuccessful attack in the first caravan raid, Muhammad entrusted a party of sixty Muhajirun led by Ubaydah to conduct another operation at a Quraysh caravan that was returning from Syria and protected by two hundred armed men. The leader of this caravan was Abu Sufyan ibn Harb. The Muslim party went as far as Thanyatul-Murra, a watering place in Hejaz. No fighting took place, as the Quraysh were quite far from the place where Muslims were in the offing to attack the caravan. Nevertheless, Sa`d ibn Abi Waqqas shot an arrow at the Quraysh. This is known as the first arrow of Islam. Despite this surprise attack, no fighting took place and the Muslims returned empty-handed. It is believed that Ubaydah was the first to carry the banner of Islam; others say Hamzah was the first to carry the first banner .
