Sura 16 Aya 103

Translator	Translation
Ali Quli Qara'i	We certainly know that they say, ‘It is only a human that instructs him.’ The language of him to whom they refer is non-Arabic, while this is a clear Arabic language.
Pickthal	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.
Shakir	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.
Yusufali	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.
