Remembrance of Allah's blessings in this world and indicators of divine power

We have created night and day as two signs, then We efface the sign of the night, and make the sign of the day resplendent that you may seek the bounty of your Lord, and know the computation of years and numbers. We have expounded most distinctly everything.

Round each man's neck We have hung his ledger of deeds, and on the Day of Resurrection will present it as a book spread out (and say):

"Read your ledger; this day you are sufficient to take your own account.

"He who finds the right path does so for himself; and he who goes astray does so to his own loss; and no one who carries a burden bears another's load. We never punish till We have sent a messenger.

"And when We destroy a human habitation We send Our command to (warn) its people living a life of ease; and when they disobey, the sentence against them is justified, and We destroy them utterly.

"How many generations have We laid low after Noah, for your Lord knows and notices well enough the sins of His creatures.
