Qur’anic exegets maintain that “non-Arabic” indicates any tongue other than Arabic, e.g. Persian and Turkish; however, the Holy Qur’an was revealed in the Arabic tongue since the Noble Prophet (S) was an Arab by descent.
The blessed Verse apparently makes a reference to the Arabs who, despite the revelation of the Holy Qur’an in eloquent Arabic, noticed that it is so eloquent in terms of form and meaning that it was hard for them to fully comprehend it hence they asked whey Qur’anic Verses were not quite intelligible to them. Thus, God Almighty addresses His Messenger (S) and says unto him: “O Muhammad!
Say unto them that the Qur’an is a healing and guidance to those who believe.” It apparently indicates that the Holy Qur’an is the Path of guidance, happiness, and righteousness and its propagation may heal disbelievers’ hearts and absolve them of their impurities. In fact, the Holy Qur’an is addressed to them through which they may find the path toward happiness and may thereby attain to their main goal.
It is worthy of note that any sound mind may comprehend the inimitability of the Holy Qur’an and anyone who fails to believe in Qur’anic Verses suffer from defects in their perceptive faculties such that they fail to perceive its message through their ears and hearts. Upon the recitation of the Holy Qur’an, they are as if they hear sounds and voices from afar but fail to comprehend the messages, since their ears and hearts fail to perceive the inimitability of the Qur’an, hence their disbelief.
But truly, they are in grave doubt [and suspicion] thereto [the Qur’an]. Familiarity with the history of Prophets is a source of consolation to the Noble Prophet (S) and Muslims. Divine Lordship grants respites to sinners so that they may repent and attain to spiritual growth. God Almighty grants respites to sinners to repent otherwise they had no way to turn to repentance.
