Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 So wait patiently for the command of your Lord, and do not yield to anyone among them who is sinful or ungrateful; 24 And celebrate the name of thy 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 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous day. 27 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 Surely this is a reminder, so whoever pleases takes to his Lord a way. 29 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 30 He makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
