Abd Allah ibn Abi Quhafa, commonly known by his kunya Abu Bakr, was the first caliph, ruling from 632 until his death in 634. As a senior companion of Muhammad and, through his daughter Aisha, also his father-in-law, Abu Bakr is referred to with the honorific title al-Siddiq by Sunni Muslims.

The Rashidun Caliphate was the first caliphate to succeed the Islamic prophet Muhammad. It was ruled by the first four successive caliphs of Muhammad after his death in 632 CE. During its existence, the empire was the most powerful economic, cultural, and military force in West Asia and Northeast Africa.
