10:57
O mankind! Verily has come to you an instruction from your Lord, and a healing for what (is) in your breasts, and guidance and mercy for the believers.
41:44
And if We (had) made it a Quran (in) a foreign (language), they (would have) said, "Why not are explained in detail its verses? (Is it) a foreign (language) and an Arab?" Say, "It (is) for those who believe, a guidance and a healing." And those who (do) not believe, in their ears (is) deafness, and it (is) for them blindness. Those are being called from a place far."
