Quotes & Sayings About Preaching Islam

It may happen that the enemies of Islam may consider it expedient not to take any action against Islam, if Islam leaves them alone in their geographical boundaries to continue the lordship of some men over others and does not extend its message and its declaration of universal freedom within their domain. But Islam cannot agree to this unless they submit to its authority by paying Jizyah, which will be a guarantee that they have opened their doors for the preaching of Islam and will not put any obstacle in its way through the power of the state. — Sayyid Qutb

Did the latter[The Messenger] have a predecessor, who envisaged
revelation as taking place by direct contact with a divine being rather than by
a book being sent down (whether as a whole or in instalments), who claimed
to have enjoyed such contact himself and who objected to the pagan angels -
not because they violated the dividing line between God and created beings
but rather because they were female? We do not hear of such a predecessor
elsewhere in the Quran, but we do learn that the Messenger had competitors in
his own time, at least in Yathrib (2:79, where they share his concept of revelation
as a book), so there is nothing implausible about the proposition that there
were preachers before him too, including some whose preaching anticipated
features of his own. — Patricia Crone

The fact is, the great intellectuals of the western religious tradition from Augustine to Aquinas and Peter Abelard became philosophically dominant. The intellectual tradition was preserved. The great intellectuals of the Islamic tradition like Averroes and Avicenna became heretics whose influence disappeared under the weight of rote preaching and practice. Islam as a result has a moral code, a legalistic system of right and wrong, but no evolved ethical tradition. — R. Joseph Hoffmann

Muhammad was not yet establishing a new religion; he was calling for sweeping social reforms. He was not yet preaching monotheism; he was demanding economic justice. — Reza Aslan
