Tafsir of Qaf 50:22

Indeed you were heedless of this. Now We have removed from you, your covering, and sharp is your sight this Day! is directed at humanity. Allah said,

لقد كنت في غفلة من هذا

(Indeed you were heedless of this), i.e. of this Day,

فكشفنا عنك غطاءك فبصرك اليوم حديد

(Now We have removed from you, your covering, and sharp is your sight this Day!) `your sight is now clear and strong.' Everyone, including the disbelievers, will have clear sight on the Day of Resurrection. However, having sight will not be helpful to the disbelievers on that Day, for Allah the Exalted said,

أسمع بهم وأبصر يوم يٲتوننا

How clearly will they (disbelievers) see and hear, the Day when they will appear before Us! (19:38), and,

ولو ترى إذ المجرمون ناكسوا رءوسهم عند ربهم ربنا أبصرنا وسمعنا فارجعنا نعمل صلحا إنا موقنون

And if you only could see when the criminals hang their heads before their Lord (saying): "Our Lord! We have now seen and heard, so send us back (to the world), that we will do righteous good deeds. Verily, we now believe with certainty. (32:12)
