No doubt, Allah Ta’ ala had blessed His Messengers (علیہم السلام) specially the Last among them ﷺ with the knowledge of many things from the Unseen, more than the knowledge of all angels and prophets, but it is obvious that the knowledge of anyone cannot be equal to that of Allah, nor it can ever be. Otherwise, this will become the kind of excess the Christians committed in their reverence for the prophet when they started equating the prophet with God. This is Shirk. May Allah keep all of us protected from it.

Covered this far was the subject of the first verse as explained above. The second verse (60) describes Allah's attribute of power which is also exclusive to Him. It is said:

وَهُوَ الَّذِي يَتَوَفَّاكُم بِاللَّيْلِ وَيَعْلَمُ مَا جَرَ‌حْتُم بِالنَّهَارِ‌ ثُمَّ يَبْعَثُكُمْ فِيهِ لِيُقْضَىٰ أَجَلٌ مُّسَمًّى

And He is the One who takes you away by night and knows what you do by day, then He makes you rise therein, so that a fixed term may be fulfilled.

Hence, at work here is nothing but the most perfect power of Allah Ta` ala which has opened a window to what happens to human beings in life, in death and in rising again. Everyone sees it every day. According to Hadith, sleep is similar to death in that it does suspend the human body as it would be in death.

By giving an example of sleeping then waking up in this verse, Allah Ta` ala has alerted human beings that the way everyone, every night and every morning, witnesses the spectacle of personally rising up from simulated death (sleep), so it should not be difficult to visualise the certainty of collective death, and then, collective rising after it, which is called Qiyamah or the Last Day. The argument is: The Supreme Being who can make this happen, could make that happen too. With His most perfect Power, this is as it shall be. Therefore, towards the end of the verse it was said:

ثُمَّ إِلَيْهِ مَرْ‌جِعُكُمْ ثُمَّ يُنَبِّئُكُم بِمَا كُنتُمْ تَعْمَلُونَ

(Thereafter, to Him you are to return; then He will tell you what you have been doing) meaning thereby that there will be the reckoning of deeds, then, will come their rewards and punishments.
