And if We had appointed it a Lecture in a foreign tongue they would assuredly have said: If only its verses were expounded (so that we might understand)? What! A foreign tongue and an Arab? - Say unto them (O Muhammad): For those who believe it is a guidance and a healing; and as for those who disbelieve, there is a deafness in their ears, and it is blindness for them. Such are called to from afar.
