Surely your Lord knows that you stand in prayer for nearly two-thirds of the night, or sometimes half of it, or a third, as do some of those with you. Allah alone keeps a precise measure of the day and night. He knows that you believers are unable to endure this, and has turned to you in mercy. So recite in prayer whatever you can from the Quran. He knows that some of you will be sick, some will be travelling throughout the land seeking Allah’s bounty, and some fighting in the cause of Allah. So recite whatever you can from it. And continue to perform regular prayers, pay alms-tax, and lend to Allah a good loan. Whatever good you send forth for yourselves, you will find it with Allah far better and more rewarding. And seek Allah’s forgiveness. Surely Allah is All-Forgiving, Most Merciful. [Surah al-Muzzammil, Verse 20]
