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

Indeed, your Lord knows, [O Muḥammad], that you stand [in prayer] almost two thirds of the night or half of it or a third of it, and [so do] a group of those with you. And Allāh determines [the extent of] the night and the day. He has known that you [Muslims] will not be able to do it¹ and has turned to you in forgiveness, so recite what is easy [for you] of the Qur’ān. He has known that there will be among you those who are ill and others traveling throughout the land seeking [something] of the bounty of Allāh and others fighting for the cause of Allāh. So recite what is easy from it and establish prayer and give zakāh and loan Allāh a goodly loan.² And whatever good you put forward for yourselves - you will find it with Allāh. It is better and greater in reward. And seek forgiveness of Allāh. Indeed, Allāh is Forgiving and Merciful.
