And to Allah belong the unseen [aspects] of the heavens and the earth and to Him will be returned the matter, all of it, so worship Him and rely upon Him. And your Lord is not unaware of that which you do.
Chapter 11 Hūd : Verse 123
Allah, the Exalted, informs that He is the All-Knower of the unseen of the heavens and the earth
He explains that everyone who does a deed, He will give them their deed (reward for it) on the Day of Reckoning. Unto Him belongs the creation and the command. Then He, the Exalted, commands that He should be worshipped and relied upon, for verily, He is sufficient for whoever trusts and turns to Him. Concerning His statement,
(And your Lord is not unaware of what you do.) This means, `The lies (of the disbelievers) against you O Muhammad are not hidden from Him. He is the All-Knower of the conditions of His creatures and He will give them the perfect recompense for their deeds in this life and the Hereafter. He will aid you (Muhammad) and His party over the disbelievers in this life and in the Hereafter.’
