54. This is the kind of the stubbornness that the Prophet (peace be upon him) was confronting. The disbelievers said: Muhammad (peace be upon him) is an Arab. Arabic is his mother tongue. How can one believe that the Arabic Quran that he presents has not been forged by himself but has been revealed to him by God? The Quran could be believed to be the revelation of God if he had started speaking fluently in a foreign language unknown to him, like Persian, Latin, or Greek. This argument of theirs has been refuted by Allah, saying: Now when the Quran has been sent down in their own tongue so that they may understand it, they raise the objection: Why has it been sent down to an Arab in Arabic? But if it had been sent down in a foreign tongue, these very people would have said: How strange! An Arab Messenger has been sent to the Arabs, but the revelations being sent to him are in a tongue which is neither understood by him nor by his people.
