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 Jews to whom We gave the Torah and those Christians to whom We gave the Gospel, rejoice in what has been revealed to you, O Messenger, because it conforms to some of what was revealed to them. Some factions of the Jews and Christians deny parts of what has been revealed to you because it does not conform to their desires, or it describes them as having altered or distorted their religion. Say to them, O Messenger, Allah has only instructed me to worship Him alone, and not to associate any partners with Him. To Him alone I invite and not to anyone else. To Him alone is my return. This is what the Torah and the Gospel taught.
