Ridda wars
Alqama left Islam before or soon after the death of Muhammad. Most chiefs of the Bedouin tribes also left the faith or threw off allegiance to the Muslim state in Medina around this time, leading to the Ridda wars in which Muhammad's successor as leader of the Muslims, Abu Bakr (), dispatched expeditions to rein in the tribes. In the account placing Alqama's apostasy after Muhammad's death, he was targeted in an expedition by Khalid ibn al-Walid and consequently declared his Muslim faith and made peace with Abu Bakr. In the account placing his defection before Muhammad died, he was said to have fled to Byzantine Syria following the Battle of Hunayn. Afterward, he returned to his tribe's protection in the Najd before eventually embracing Islam once again and becoming an important ally of Abu Bakr. There was little conflict reported between the Banu Amir and Medina during the Ridda wars. A son of Yazid ibn al-Sa'iq, Mu'adh, is held to have opposed the rebellion.
