Amatul Rahmân Omer:
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.
