Edited sentence: 7th century Arab merchant who claimed to have received revelations from God through an Angel while he was meditating in a cave near Medina Arabia.He is revered by Muslims who believe him to be the final prophet of Allah (God).Non-Muslims consider Muhammad the founder of the religion of Islam; pious Muslims consider that his work merely clarified and finalized the true religion, building on the work of other prophets of monotheism, and believe Islam to have existed before Muhammad.They will often give him the title Rasūlu 'llāh, "messenger of God", and follow his name in speech and in writing with the phrase sallallahu `alayhi wa s-salām, or, if using English, "peace be upon him"
