Ridda Wars

The first Rashidun Caliph (632-634 CE) and closest companion of Prophet Muhammad. Known as 'Al-Siddiq' (The Truthful), he preserved Islamic unity after the Prophet's death, defeated the Ridda rebellions, compiled the Quran, and initiated Islamic conquests beyond Arabia.

After heavy losses among the Qur'an reciters at Yamama, Caliph Abu Bakr ordered Zayd ibn Thabit to gather the Qur'an into a single written record. The resulting suhuf was an archival master held in the caliph's keeping, not a published edition, and it became the basis of Uthman's standardisation.

Khalid ibn al-Walid (592-642 CE) was the most effective commander of the early Islamic conquests, known as the Sword of Allah after the Prophet's description of him at Mu'tah. He led Muslim forces across Arabia, Iraq, and Syria.

Nusaybah bint Ka'ab, known as Umm Ammara, was an Ansari woman of Medina who took the Second Pledge of Aqaba, fought in defence of the Prophet at Uhud, and lost a hand at Yamama. Three hadith are transmitted from her.

The first four Caliphs of Islam (632-661 CE), known as the 'Rightly-Guided Caliphs,' who succeeded Prophet Muhammad and established the foundations of Islamic civilization through unprecedented territorial expansion, administrative innovation, and preservation of Islamic teachings.

The Ridda Wars (632–633 CE / 11–12 AH) were campaigns led by the first caliph Abu Bakr to suppress rebellions across Arabia after the Prophet's death, ranging from refusal of zakat to apostasy. Fought under commanders such as Khalid ibn al-Walid, they reunified Arabia under Medinan authority.
