Major battles in the history of Islam arose between the Meccans and the Muslims; one of the most important to the latter was the Battle of Badr in 624 AD. Other early battles included battles in Uhud (625), Khandaq (627), Mecca (630) and Hunayn (630). These battles, especially Uhud was unsuccessful in comparison to the Battle of Badr. In relating this battle, the Qu'ran states that Allah sent an "unseen army of angels" that helped the Muslims defeat the Meccans.
