Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 And remember thou the name of thy Lord in the morning and in the evening. 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Surely men love what hastes away and forget the grievous day (ahead). 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 will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
