Ar-Ra'd 13:36

Wallatheena ataynahumualkitaba yafrahoona bima onzila ilaykawamina al-ahzabi man yunkiru baAAdahu qulinnama omirtu an aAAbuda Allaha wala oshrikabihi ilayhi adAAoo wa-ilayhi maab

And [the believers among] those to whom We have given the [previous] Scripture rejoice at what has been revealed to you, [O Muḥammad], but among the [opposing] factions are those who deny part of it [i.e., the Qur’ān]. Say, "I have only been commanded to worship Allāh and not associate [anything] with Him. To Him I invite, and to Him is my return."

Those to whom We have given the Book are happy with what has been sent down to you. And among their groups there are those who deny some of it. Say, “I am commanded only to worship Allah and not to ascribe partners to Him. To Him I call and to Him is my return.”
