The expedition to al-Abwa (Waddan), the first of the Prophet's campaigns

In Safar of the 2nd year AH, the Prophet set out with seventy men of the emigrants to intercept a Quraysh caravan. He reached Waddan and met no opposition. ¹

He marched from Medina to Waddan. Waddan lies twenty-nine miles from Rabigh on the Medina side. He was away for fifteen nights. ¹

He appointed Sa'd ibn Ubada over Medina, and concluded a treaty with Banu Damra. ¹

The same event is described as the expedition of al-Abwa'.
