Criticism of Islam has existed since its formative stages. Early written disapproval came from Jews and Christians, before the ninth century, many of whom viewed Islam as a radical Christian heresy, as well as by some former Muslim atheists and agnostics, such as Ibn al-Rawandi. The September 11 attacks and other terrorist attacks in the early 21st century, reignited suspicion and criticism of all of Islam, with calls for moderates to condemn the terrorism of the fundamnatalists and help prevent radicilsation and islamophobia.

However, according to Peter Adamson, Abu Bakr al-Razi may have been "deliberately misdescribed" by his fellow townsman Abu Hatim al-Razi. In this view, Abu Bakr was mainly arguing against the use of miracles to prove Muhammad's prophecy, against anthropomorphism, and against the uncritical acceptance of taqlīd vs naẓar. Abu Isa al-Warraq was a ninth-century Arab skeptic scholar and critic of Islam and religion in general. Al-Warraq also doubted claims portraying Muhammad as a prophet. Arab skeptic, rationalist philosopher and poet Al-Maʿarri (973-1057 CE) started out as a Sunni Muslim but later he repudiated Islam, became a critic of Abrahamic religions and Islam, and wrote a satire on the Qu'ran. He wrote and taught that religion itself was a "fable invented by the ancients" and that humans were "of two sorts: those with brains, but no religion, and those with
