73:20

(73:20) In fact, your Lord knows that you are idle for less than two-thirds of the Night, and its half, and its third, (as) a group of those with you. And God regulates (the order of) the Night, and the Day. He knows that you cannot count it, and (accepts) repentance for you. So create from the Quran what is feasible. He knows that among you there are those who are sick, and some who wander the earth in search of God's favor, and others who fight in the Way of God. So create out of it what is possible, and establish Prayer, and (distribute) the Cleansing Tribute, and credit God with good credit. All that is good which you prepare for yourselves, you will find with God. This (will prove to be) the best, and a great reward. And ask God for forgiveness. Indeed, God is a forgiving, merciful God.
