We have revealed the Qur'an to you gradually; 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 and glorify 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 Verily they love (the good of this world) that is hastily obtainable and are oblivious of the burdensome Day ahead of them. 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 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He will admit to His Mercy whom He will and as for the Zalimun, (polytheists, wrong-doers, etc.) He has prepared a painful torment. 31
