Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 and remember the name of your Lord, morning and evening; 25 And during night, prostrate yourself to Him (i.e. the offering of Maghrib and 'Isha' prayers), and glorify Him a long night through (i.e. Tahajjud prayer). 26 Surely men love what hastes away and forget the grievous day (ahead). 27 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
