We have revealed the Qur'an to you gradually; 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 And remember the Name of thy Lord at dawn and in the 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 is We Who creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 28 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 But you cannot will it unless God wills [to show you that way]: for, behold, God is indeed all-seeing, wise. 30 He maketh whom He will to enter His mercy, and for evil-doers hath prepared a painful doom. 31
