Had We revealed it as a non-Arabic Quran, they would have certainly argued, “If only its verses were made clear ˹in our language˺. What! A non-Arabic revelation for an Arab audience!” Say, ˹O Prophet,˺ “It is a guide and a healing to the believers. As for those who disbelieve, there is deafness in their ears and blindness to it ˹in their hearts˺. It is as if they are being called from a faraway place.”10
Had We sent this as a Qur´an (in the language) 4516 other than Arabic, they would have said: "Why are not its verses explained in detail? What! (a Book) not in Arabic and (a Messenger an Arab?" Say: "It is a Guide and a Healing to those who believe; and for those who believe not, there is a deafness in their ears, 4517 and it is blindness in their (eyes): They are (as it were) being called from a place far distant!"
4516 Cf. 16:103-105; 12:2; etc. It was most natural and reasonable that the Messenger being Arab, the Message should be in his own tongue, that he might explain it in every detail, with the greatest power and eloquence. Even though it was to be for the whole world, its initial exposition was thus to be in Arabic. But if people had no faith and were spiritually deaf or blind, it would not matter in what language it came.
4517 Cf. 41:5, and 6:25 . They pretended that it was too deep for them, when they meant that they were superior to it! The fact was that by putting themselves in an artificially false position, they rendered themselves impervious to the Message. The voice of Revelation or the voice of conscience sounded to them as if it came from a far-off place! They themselves made themselves strangers to it.
Now if We had willed this [divine writ] to be a discourse in a non-Arabic tongue, they [who now reject it] would surely have said, “Why is it that its messages have not been spelled out clearly? 37 Why - [a message in] a non-Arabic tongue, and [its bearer] an Arab?” Say: “Unto all who have attained to faith, this [divine writ] is a guidance and a source of health; but as for those who will not believe - in their ears is deafness, and so it remains obscure to them: they are [like people who are] being called from too far away. 38
37 Sc., "in a tongue which we can understand". Since the Prophet was an Arab and lived in an Arabian environment, his message had to be expressed in the Arabic language, which the people to whom it was addressed in the first instance could understand: see in this connection note 72 on the first sentence of 13:37, as well as the first half of 14:4 - "never have We sent forth any apostle otherwise than [with a message] in his own people’s tongue, so that he might make [the truth] clear unto them". Had the message of the Qur’an been formulated in a language other than Arabic, the opponents of the Prophet would have been justified in saying, "between us and thee is a barrier" (verse 5 of this surah).
38 Lit., "from a far-off place": i.e., they only hear the sound of the words, but cannot understand their meaning.
10 So they neither hear nor understand the call.
