103وَلَقَد نَعلَمُ أَنَّهُم يَقولونَ إِنَّما يُعَلِّمُهُ بَشَرٌ ۗ لِسانُ الَّذي يُلحِدونَ إِلَيهِ أَعجَمِيٌّ وَهٰذا لِسانٌ عَرَبِيٌّ مُبينٌ(Saheeh International)And We certainly know that they say, "It is only a human being who teaches him [i.e., the Prophet (ṣ)]." The tongue of the one they refer to is foreign,1 and this [recitation, i.e., Qur’ān] is [in] a clear Arabic language. Having seen the Prophet (ṣ) speaking with a foreign man on occasion, the Quraysh accused him of repeating the man's words.
