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 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 Surely these men love the hasty world, and leave be behind them a heavy 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 it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
