(Muhammad), We have revealed the Quran to you in gradual steps. 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 Mention the Name of your Lord, mornings and evenings. 25 And during the night - worship Him; and hallow Him the livelong night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind 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 is indeed an advice; so whoever wishes may take the path towards his Lord. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
