VERILY, [O believer,] it is We who have bestowed from on high this Qur'an upon thee, step by step - truly a bestowal from on high! 23 Therefore stay patient upon your Lord’s command, and do not listen to any of the sinners or ingrates among them. 24 And celebrate the name of thy Lord morning and evening, 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Verily those love the herein, and leave in front of them a heavy day. 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 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 But you will not unless God wills; surely God is ever All-knowing, All-wise. 30 He admits whoever He will into His grace and has prepared a painful punishment for the evil doers. 31
