And even if We opened to them a gate to the heavens and they were to continue ascending through it (all day long)(14)They would surely say (in the evening): "Our eyes have been (as if) dazzled (we have not seen any angel or heaven). Nay, we are a people bewitched. (15)

Allah explains the extent of their disbelief and stubborn resistance to the truth by stating that even if a door to heaven were to be opened for them, and they were to be taken up through it, they would still not believe. Rather, they would say:

إِنَّمَا سُكِّرَتْ أَبْصَارُنَا

(Our eyes have been (as if) dazzled.) Mujahid, Ibn Kathir and Ad-Dahhak said, "[this means] our vision has been blocked." Qatadah narrated that Ibn 'Abbas said, "[this means] our eyesight has been taken away." Al-'Awfi reported that Ibn 'Abbas said, "[this means] we were confused and put under a spell."

سُكِّرَتْ أَبْصَارُنَا

(Our eyes have been (as if) dazzled.) Ibn Zayd said: "The one who is dazzled [lit. intoxicated] is the one who cannot reason."
