Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And remember the Name of thy Lord at dawn and in the evening 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous day. 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 This is a reminder. Let whoever wishes, take the right path to his Lord. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
