Al-Muzzammil 73:20 ۞ ان ربك يعلم انك تقوم ادنى من ثلثي الليل ونصفه وثلثه وطايفة من الذين معك والله يقدر الليل والنهار علم ان لن تحصوه فتاب عليكم فاقرءوا ما تيسر من القران علم ان سيكون منكم مرضى واخرون يضربون في الارض يبتغون من فضل الله واخرون يقاتلون في سبيل الله فاقرءوا ما تيسر منه واقيموا الصلاة واتوا الزكاة واقرضوا الله قرضا حسنا وما تقدموا لانفسكم من خير تجدوه عند الله هو خيرا واعظم اجرا واستغفروا الله ان الله غفور رحيم ٢٠

Verily, your Lord knows that you do stand (to pray at night) a little less than two thirds of the night, or half the night, or a third of the night, and also a party of those with you. And Allâh measures the night and the day. He knows that you are unable to pray the whole night, so He has turned to you (in mercy). So, recite you of the Qur’ân as much as may be easy for you. He knows that there will be some among you sick, others travelling through the land, seeking of Allâh’s Bounty, yet others fighting in Allâh’s Cause. So recite as much of the Qur’ân as may be easy (for you), and perform As-Salât (Iqâmat-as-Salât ) and give Zakât, and lend to Allâh a goodly loan. And whatever good you send before you for yourselves (i.e. Nawâfil non-obligatory acts of worship: prayers, charity, fasting, Hajj and ‘Umrah), you will certainly find it with Allâh, better and greater in reward. And seek Forgiveness of Allâh. Verily, Allâh is Oft-Forgiving, Most-Merciful¹.
