كَوْنُ الْمُقَدَّمِ مَحَطَّ الْإِنْكَارِ وَالتَّعَجُّبِ
Making the advanced phrase the focus of denial and surprise.
أَبَعْدَ طُولِ التَّجْرِبَةِ تَنْخَدِعُ بِهَذِهِ الزَّخَارِفِ؟
After so much experience, are you still deceived by these ornaments?
The surprising point is not merely being deceived, but being deceived despite lengthy experience. The prepositional phrase about experience is consequently placed before the verb.
Word order distinguishes a plain report of the action from astonishment at its occurrence under a particular, unexpected circumstance.
