وَلَقَدْ نَعْلَمُ أَنَّهُمْ يَقُولُونَ إِنَّمَا يُعَلِّمُهُ بَشَرٌ ۗ لِسَانُ الَّذِي يُلْحِدُونَ إِلَيْهِ أَعْجَمِيٌّ وَهَٰذَا لِسَانٌ عَرَبِيٌّ مُبِينٌ
Yet We know what they say: "It is only a man who instructs him." The speech of the man they imply is obscure while this is clear Arabic.
Certainly We know that they say, "It is but a human being that teaches him." But the tongue of him to whom they falsely hint is outlandish, while this (Qur’an) is in clear Arabic tongue.
And We know fully well what they say (by way of objection) that this (Qur´ân) is (not revealed by God but it is) only what a human being instructs to him (- to Muhammad). But (strange it is) that the tongue of him to whom they (unjustly) allude (of making this insinuation) is foreign and wanting in clearness, whereas the language of this (Qur´ân) is chaste Arabic, plain and clear.
And, indeed, full well do We know that they say, "It is but a human being that imparts [all] this to him!" 129 - [notwithstanding that] the tongue of him to whom they so maliciously point is wholly outlandish, 130 whereas this is Arabic speech, clear [in itself] and clearly showing the truth [of its source]. 131
And assuredly We know that they say: it is only a human being who teachech him. The speech of him unto whom they incline is foreign while this is Arabic speech plain.
And indeed We know that they say, "This Qur’an is being taught by some other man"; the one they refer to speaks a foreign language, whereas this is clear Arabic!
We know well that they say, "It is only some mortal who teaches him." But the tongue of him they point to (Muhammad) is outlandish, while this (Quran) is Arabic, pure and clear.
And We have known that they say: "But/indeed a human teaches/instructs him, (the) tongue/language/speech (of) those who deviate, insult and defame to Him, non-Arabic/Persian (tongue/language/speech), and this (is) an Arabic clear/evident tongue/language/speech.
We know very well what they say about you, O Muhammad: "A certain man teaches him." But the man they allude to speaks a foreign language while this (The Qur'an) is in eloquent Arabic.
Say: The Holy Spirit has revealed it from thy Lord with truth, that it may establish those who believe, and as a guidance and good news for those who submit.
We know that they say a mere mortal has taught it (the Quran) to him (Muhammad). The language of the person whom they think has taught it to him is not Arabic. This (the Quran) is in illustrious Arabic.
And We know well that they say: Only a man teacheth him. The speech of him at whom they falsely hint is outlandish, and this is clear Arabic speech.
And certainly We know that they say: Only a mortal teaches him. The tongue of him whom they reproach is barbarous, and this is clear Arabic tongue.
And indeed We know that they (polytheists and pagans) say: "It is only a human being who teaches him (Muhammad)." The tongue of the man they refer to is foreign, while this (the Qur'an) is a clear Arabic tongue.
We know indeed that they say, "It is a man that teaches him." The tongue of him they wickedly point to is notably foreign, while this is Arabic, pure and clear.
