Indeed your Lord knows that you stand vigil nearly two thirds of the night —or [at times] a half or a third of it— along with a group of those who are with you. Allah measures the night and the day. He knows that you cannot calculate it [exactly], and so He was lenient toward you. So recite as much of the Qurʾān as is feasible. He knows that some of you will be sick, while others will travel in the land seeking Allah’s grace, and yet others will fight in the way of Allah. So recite as much of it as is feasible, and maintain the prayer and pay the zakāt and lend Allah a good loan. Whatever good you send ahead for your souls you will find it with Allah [in a form] that is better and greater with respect to reward. And plead to Allah for forgiveness; indeed Allah is all-forgiving, all-merciful.
