ثُمَّ ارْجِعِ الْبَصَرَ كَرَّتَيْنِ يَنقَلِبْ إِلَيْكَ الْبَصَرُ خَاسِأً وَهُوَ حَسِيرٌ
[67:4]
Then turn back the eye again and again; your look shall '~ come back to you confused while it is fatigued.
Again turn thy vision a second time: (thy) vision will come back to thee dull and discomfited, in a state worn out.
Then look again and yet again, thy sight will return unto thee weakened and made dim.
