﴿ وَلَوْ جَعَلْنَٰهُ قُرْءَانًا أَعْجَمِيًّۭا لَّقَالُوا۟ لَوْلَا فُصِّلَتْ ءَايَٰتُهُۥٓ ۖ ءَا۬عْجَمِىٌّۭ وَعَرَبِىٌّۭ ۗ قُلْ هُوَ لِلَّذِينَ ءَامَنُوا۟ هُدًۭى وَشِفَآءٌۭ ۖ وَٱلَّذِينَ لَا يُؤْمِنُونَ فِىٓ ءَاذَانِهِمْ وَقْرٌۭ وَهُوَ عَلَيْهِمْ عَمًى ۚ أُو۟لَٰٓئِكَ يُنَادَوْنَ مِن مَّكَانٍۭ بَعِيدٍۢ ﴾

“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? 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.”

When the Quran was revealed in the Arabic language, opponents of Islam said that this was the Prophet Muhammad’s mother tongue, and therefore it was not difficult for him to write some sort of book in Arabic and present it as holy scripture. They further said that had he really been a prophet, he would have delivered discourses in a strange language with the help of God. Non-serious and insincere people alone indulge in such talk, and such people can never be satisfied. For example, if it had happened that the prophet had approached the Arab people and started talking to them in Greek or Syriac or Persian language, the people would have had grounds for saying; ‘How strange is this prophet! He says that he has come to guide the people, but he speaks in a language which is not understood by his audience.’ The fact is that only those people are able to accept the Truth who are serious about it. Those who are not serious about the Truth are unable to understand even the clearest of its points. The analogy befitting them is that of a person who is called from a very far-off place. Such a person will hear some voice, but he will be unable to make out its real sense.
