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

Thy Lord doth know that thou standest forth (to prayer) nigh two-thirds of the night, or half the night, or a third of the night, and so doth a party of those with thee. But Allah doth appoint night and day in due measure He knoweth that ye are unable to keep count thereof. So He hath turned to you (in mercy): read ye, therefore, of the Qur'an as much as may be easy for you. He knoweth that there may be (some) among you in ill-health; others travelling through the land, seeking of Allah's bounty; yet others fighting in Allah's Cause, read ye, 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 ye send forth for your souls ye shall find it in Allah's Presence,- yea, better and greater, in Reward and seek ye the Grace of Allah: for Allah is Oft-Forgiving, Most Merciful.
