Quran 29:46 — The Spider (Al-'Ankaboot)

Do not argue with the people of the scripture (Jews, Christians, and Muslims) except in the nicest possible manner—unless they transgress—and say, "We believe in what was revealed to us and in what was revealed to you, and our god and your god is one and the same; to Him we are submitters."

[29:45] You shall recite what is revealed to you of the scripture, and observe the Contact Prayers (Salat), for the Contact Prayers prohibit evil and vice. But the remembrance of GOD (through Salat) is the most important objective.* GOD knows everything you do.

[29:47] We have revealed to you this scripture, and those whom we blessed with the previous scripture will believe in it. Also, some of your people will believe in it. Indeed, those who disregard our revelations are the real disbelievers.
