Ridda wars

Troubles emerged soon after Abu Bakr's succession, with several Arab tribes launching revolts, threatening the unity and stability of the new community and state. These insurgencies and the caliphate's responses to them are collectively referred to as the Ridda wars ("Wars of Apostasy").

The opposition movements came in two forms. One type challenged the political power of the nascent caliphate as well as the religious authority of Islam with the acclamation of rival ideologies, headed by political leaders who claimed the mantle of prophethood in the manner that Muhammad had done. These rebellions include:

These leaders are all denounced in Islamic histories as "false prophets".

The second form of opposition movement was more strictly political in character. Some of the revolts of this type took the form of tax rebellions in Najd among tribes such as the Banu Fazara and Banu Tamim. Other dissenters, while initially allied to the Muslims, used Muhammad's death as an opportunity to attempt to restrict the growth of the new Islamic state. They include some of the Rabīʿa in Bahrayn, the Azd in Oman, as well as among the Kindah and Khawlan in Yemen.

Abu Bakr, likely understanding that maintaining firm control over the disparate tribes of Arabia was crucial to ensuring the survival of the state, suppressed the insurrections with military force. He dispatched Khalid ibn Walid and a body of troops to subdue the uprisings in Najd as well as that of Musaylimah, who posed the most serious threat. Concurrent to this, Shurahbil ibn Hasana and Al-Ala'a Al-Hadrami were sent to Bahrayn, while Ikrimah ibn Abi Jahl, Hudhayfah al-Bariqi and Arfaja al-Bariqi were instructed to conquer Oman. Finally, Al-Muhajir ibn Abi Umayya and Khalid ibn Asid were sent to Yemen to aid the local governor in re-establishing control. Abu Bakr also made use of diplomatic means in addition to military measures. Like Muhammad before him, he used marriage alliances and financial incentives to bind former enemies to the caliphate. For instance, a member of the Banu Hanifa who had sided with the Muslims was rewarded with the granting of a land estate. Similarly, a Kindah rebel named Al-Ash'ath ibn Qays, after repenting and re-joining Islam, was later given land in Medina as well as the hand of Abu Bakr's sister Umm Farwa in marriage.

At their heart, the Ridda movements were challenges to the political and religious supremacy of the Islamic state. Through his success in suppressing the insurrections, Abu Bakr had in effect continued the political consolidation which had begun under Muhammad's leadership with relatively little interruption. By wars' end, he had established an Islamic hegemony over the entirety of the Arabian Peninsula.
