Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 23 therefore be patient under the Judgement of your Lord, and do not obey either the sinner or the unbeliever. 24 And remember thou the name of thy Lord in the morning and in the 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, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 28 This chapter is a reminder. Let those who want, seek guidance from their Lord. 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 He admits whoever He will into His grace and has prepared a painful punishment for the evil doers. 31
