Ridda wars
The traditional sources place the final suppression of the Arab tribes of the Ridda wars before March 633, though the Western historian Leone Caetani insists the campaigns must have continued into 634. The Muslim war efforts, in which Khalid played a vital part, secured Medina's dominance over the strong tribes of Arabia, which sought to diminish Islamic authority in the peninsula, and restored the nascent Muslim state's prestige. According to Lecker, Khalid and the other Qurayshite generals "gained precious experience [during the Ridda wars] in mobilising large multi-tribal armies over long distances" and "benefited from the close acquaintance of the Kuraysh "[sic]" with tribal politics throughout Arabia".
