Look how they went astray because of the comparisons (incorrect evaluations) they made to you! They can no longer find a way out!
Sayyed Abbas Sadr-Ameli
Behold, how they strike similitudes for you, but they have gone astray, so they shall not be able to find a way (to the truth)
Al-muntakhab fi tafsir al-Qur'an al-Karim
Look how they describe you O Muhammad in -irrelevant- similies reflecting deviation of mind and thought that they are unable to strike on the path of truth guiding into all truth
Or (why has not) a treasure been thrown down to him or (why is there no) garden for him from which he could eat?" And those who are unjust say, "You follow none but a man under the influence of magic."
