Fussilat · 41:44

44. Had I revealed this Qur’ān in a language other than that of the Arabs, the disbelievers among them would have said, “Why are its verses not made clear to us so that we can understand them?” Can the Qur’ān be in any language other than Arabic, while the one who brings it is an Arab? O Messenger! Say to these people: For those people who bring faith in Allah and believe in His messengers, the Qur’ān is a guidance from deviance and a cure for the ignorance and its consequences in the hearts. As for those who do not have faith in Allah, their ears are deaf and they are blinded from it so they do not understand it. These people are called from a distant place, so how could they hear the voice of the caller?
