Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 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 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 We created them and made firm their make, and when We please We will bring in their place the likes of them by a change. 28 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
