Battle of Yamama

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 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.
