Indeed, the religion in the sight of Allāh is Islām. And those who were given the Scripture did not differ except after knowledge had come to them - out of jealous animosity between themselves. And whoever disbelieves in the verses of Allāh, then indeed, Allāh is swift in [taking] account.
So if they argue with you, say, "I have submitted myself to Allāh [in Islām], and [so have] those who follow me." And say to those who were given the Scripture and [to] the unlearned, "Have you submitted yourselves?" And if they submit [in Islām], they are rightly guided; but if they turn away - then upon you is only the [duty of] notification. And Allāh is Seeing of [His] servants.
