The Abrahamic religions are a group of religions centered around the worship of the God of Abraham. Abraham, a Hebrew patriarch, is extensively mentioned throughout the Abrahamic religious scriptures of the Quran, and the Hebrew and Christian Bibles. Jewish tradition claims that the Twelve Tribes of Israel are descended from Abraham through his son Isaac and grandson Jacob, whose sons formed the nation of the Israelites in Canaan (or the Land of Israel); Islamic tradition claims that twelve Arab tribes known as the Ishmaelites are descended from Abraham through his son Ishmael in the Arabian Peninsula. In its early stages, the Israelite religion was derived from the Canaanite religions of the Bronze Age; by the Iron Age, it had become distinct from other Canaanite religions as it shed polytheism for monolatry. The monolatrist nature of Yahwism was further developed in the period following the Babylonian captivity, eventually emerging as a firm religious movement of monotheism. In the 1st century CE, Christianity emerged as a splinter movement out of Judaism in the Land of Israel, developed under the Apostles of Jesus of Nazareth; it spread widely after it was adopted by the Roman Empire as a state religion in the 4th century CE. In the 7th century CE, Islam was founded by Muhammad in the Arabian Peninsula; it spread widely through the early Muslim conquests, shortly after his death. Alongside the Indian religions, the Iranian religions, and the East Asian religions, the Abrahamic religions make up the largest major division in comparative religion. By total number of adherents, Christianity and Islam comprise the largest and second-largest religious movements in the world, respectively. Abrahamic religions with fewer adherents include Judaism, the Baháʼí Faith, Druzism, Samaritanism, and Rastafari. The Catholic scholar of Islam Louis Massignon stated that the phrase "Abrahamic religion" means that all these religions come from one spiritual source.
