Your Lord knows that you stand up praying for nearly two-thirds of the night, or one-half of it and sometimes one third of it, as do others among your followers. God determines the measure of night and day. He knows that you will not be able to do it, so He has turned to you in mercy. Recite, then, as much of the Quran as is easy for you. He knows that there will be some among you who may be sick and others who will be travelling throughout the land seeking God's bounty, and yet others who may be fighting for the cause of God. So, recite, then as much of it as you are able, and be constant in prayer, and spend in charity, and give to God a goodly loan. For whatever good deed you send on before you for your souls, you will find it with God. It will be improved and richly rewarded by Him. Seek God's forgiveness, He is most forgiving, most merciful.
