(O Prophet), indeed We have revealed the Qur'an to you in portions. 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 Remember the name of thy Lord at morn 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 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 But you cannot will, unless Allah wills. Verily, Allah is Ever All-Knowing, All-Wise. 30 He maketh whom He will to enter His mercy, and for evil-doers hath prepared a painful doom. 31
