Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 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 These people (disbelievers) love the worldly life and neglect the terrifying day which will come. 27 We created them and fixed their bones and joints; and We could replace them when We like with others like them. 28 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
