Your Lord knows that you stand forth (to prayer) nearly two-thirds of the night, or half the night, or a third of the night, and so does a party of those with you. But Allah appoints Night and Day in due measure. He knows that you are unable to keep count thereof. So He has turned to you (in mercy): you read, therefore, of the Quran an as much as may be easy for you. He knows that there may be (some) among you in ill-health; others traveling through the land, seeking of Allah’s bounty; yet others fighting in Allah’s Cause. You read, therefore, as much of the Qur’an as may be easy (for you); and establish regular Prayer and give regular Charity; and loan to Allah, a Beautiful Loan. And whatever good you send forth for your souls, you shall find it in Allah’s Presence, - yes, better and greater, in Reward. And you seek the forgiveness of Allah: for Allah is Oft-Forgiving, Most Merciful.
