Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And glorify the name of your Lord morning and evening. 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 27 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 But you cannot will it unless God wills [to show you that way]: for, behold, God is indeed all-seeing, wise. 30 He admits unto His grace everyone who wills [to be admitted]; but as for the evildoers - for them has He readied grievous suffering [in the life to come]. 31
