Surah An-Nahl Verse 103

وَلَقَدْ نَعْلَمُ أَنَّهُمْ يَقُولُونَ إِنَّمَا يُعَلِّمُهُ بَشَرٌ ۗ لِّسَانُ الَّذِي يُلْحِدُونَ إِلَيْهِ أَعْجَمِيٌّ وَهَٰذَا لِسَانٌ عَرَبِيٌّ مُّبِينٌ

Wa laqad na'lamu annahum yaqooloona innamaa yu'allimuhoo bashar; lisaanul lazee yulhidoona ilaihi a'ja miyyunw wa haaza lisaanun 'Arabiyyum mubeen

Translation / The Meaning

And We certainly know that they say, "It is only a human being who teaches the Prophet." The tongue of the one they refer to is foreign, and this Qur'an is [in] a clear Arabic language.
