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 Mention the Name of your Lord, mornings and evenings. 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 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 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He maketh whom He will to enter His mercy, and for evil-doers hath prepared a painful doom. 31
