The greatest Ayat of the Quran
Allah SWT gave us from the Quran the greatest verse or ayat from the book which is known as ayat ul kursi. It begins with the greatest name Allah and that there is no deity worthy of worship except Allah. Allah is the ever living, All sustaining meaning Allah can never die and has no beginning nor any end. Allah was present when there was no creation in existence and then Allah SWT caused the creation to come into existence and He SWT sustains everything with the entire expanse of the heavens and the earth. All matter and life is preserved and sustained by Allah.
Allah does not at anytime feel drowsy or the need to sleep. As Allah guards the entire creation and one aspect of a guard that is human is that he usually gets drowsy or falls asleep on the job, whereas for Allah SWT neither drowsiness nor sleep overtakes him and it is not befitting of these two qualities of sleep and drowsiness to have an effect on Allah SWT. The entire expanse of the heavens above and what is in entirety on the earth belongs to Allah.
There can only be intercession granted to someone with only Allahs permission. A person can only intercede for someone else on the day of judgement if Allah gives permission just like Allah will give permission to certain people like the noble Prophets upon them all be peace and for those who have memorized and preserved the entire Quran within their hearts. Allah SWT knows what is ahead and what is behind meaning past, present and future is known to Allah and no one has the capacity to grasp the knowledge of Allah except what Allah chooses to reveal to the people. The seat or the kursi of Allah encompasses the expanse of the entire heavens and the earth and the preservation of the entire creation meaning all the many billions of stars, planets and celestial bodies and everything in the observable and unobservable heavens above and everything of life and matter on the earth, every creature, lifeform and element on earth is preserved, sustained and this does not tire Allah SWT in any given moment and in fact the preservation of the entire heavens and the earth is a very easy matter for Allah SWT for Allah SWT is free from any imperfection and is All powerful, the most high, the Greatest, the Almighty.
