It is We Who have sent down the Qur'an to thee by stages. 23 So wait patiently for the command of your Lord, and do not yield to anyone among them who is sinful or ungrateful; 24 And remember thou the name of thy Lord in the morning and in the evening. 25 Prostrate before Him and glorify Him extensively during the night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 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 surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 And you do not please except that Allah please, surely Allah is Knowing, 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
