Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 Await, then, in all patience thy Sustainer's judgment, and pay no heed to any of them, who is a wilful sinner or an ingrate; 24 and glorify your 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 These people (disbelievers) love the worldly life and neglect the terrifying day which will come. 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 Indeed, this is a reminder, so he who wills may take to his Lord a way. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and 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
