Lo! We, even We, have revealed unto thee the Qur'an, a revelation; 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 And glorify the name of your Lord morning and evening. 25 And during night, prostrate yourself to Him (i.e. the offering of Maghrib and 'Isha' prayers), and glorify Him a long night through (i.e. Tahajjud prayer). 26 Surely these love the transitory and neglect a grievous day before them. 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 This is indeed a Reminder, so that he who will, takes a path to his Lord. 29 But you will not unless God wills; surely God is ever All-knowing, All-wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
