迁士是阿拉伯历史中与辅士相对应的说法，从麦加迁移到麦地那的穆斯林被称为迁士(muhājirūn)，而麦地那的穆斯林则被称为辅士(ansār)。

Muhajirun (Arabic:المهاجرون‎ The Emigrants) were the first converts to Islam and the Islamic Prophet Muhammad's advisors and relatives, who emigrated with him from Mecca to Medina, the event known in Islam as The Hijra. The early Muslims from Medina are called the Ansar ("helpers").
