Battle of Yamamah

Abu Hudhayfa ibn Utba (d. 11 or 12 AH / 632 or 633 CE) was an early Companion of Prophet Muhammad, a son of the Meccan leader Utba ibn Rabi'a, an emigrant to Abyssinia and a veteran of Badr, who freed and adopted Salim and died commanding a wing of the Muslim army at Yamamah.

The Ridda Wars (11-12 AH / 632-633 CE) were the campaigns by which the first caliph Abu Bakr suppressed the tribal revolts, zakat refusals and rival prophetic movements that broke out across Arabia after the Prophet's death, restoring Medinan authority over the peninsula in about four months.
