41:3A Scripture whose Verses are detailed, a Quran in Arabic for people who know.

41:26Those who disbelieve say, “Do not listen to this Quran, and talk over it, so that you may prevail.”

41:44Had We made it a Quran in a foreign language, they would have said, “If only its verses were made clear.” Non-Arabic and an Arab? Say, “For those who believe, it is guidance and healing. But as for those who do not believe: there is heaviness in their ears, and it is blindness for them. These are being called from a distant place.”
