Most surely in the creation of the heavens and the earth and the alternation of the night and the day, and the ships that run in the sea with that which profits men, and the water that Allah sends down from the cloud, then gives life with it to the earth after its death and spreads in it all (kinds of) animals, and the changing of the winds and the clouds made subservient between the heaven and the earth, there are signs for a people who understand.

They are not all alike; of the followers of the Book there is an upright party; they recite Allah's communications in the nighttime and they adore (Him).

Most surely in the variation of the night and the day, and what Allah has created in the heavens and the earth, there are signs for a people who guard (against evil).

Say: Tell me, if Allah were to make the night to continue incessantly on you till the day of resurrection, who is the god besides Allah that could bring you light? Do you not then hear?

Say: Tell me, if Allah were to make the day to continue incessantly on you till the day of resurrection, who is the god besides Allah that could bring you the night in which you take rest? Do you not then see?

And (in) the variation of the night and the day, and (in) what Allah sends down of sustenance from the cloud, then gives life thereby to the earth after its death, and (in) the changing of the winds, there are signs for a people who understand.

Surely your Lord knows that you pass in prayer nearly two-thirds of the night, and (sometimes) half of it, and (sometimes) a third of it, and (also) a party of those with you; and Allah measures the night and the day. He knows that you are not able to do it, so He has turned to you (mercifully), therefore read what is easy of the Quran. He knows that there must be among you sick, and others who travel in the land seeking of the bounty of Allah, and others who fight in Allah's way, therefore read as much of it as is easy (to you), and keep up prayer and pay the poor-rate and offer to Allah a goodly gift, and whatever of good you send on beforehand for yourselves, you will find it with Allah; that is best and greatest in reward; and ask forgiveness of Allah; surely Allah is Forgiving, Merciful.
