(Muhammad), We have revealed the Quran to you in gradual steps. 23 So submit patiently to thy Lord's command, and obey not of them any guilty one or disbeliever. 24 Mention the Name of your Lord, mornings and evenings. 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 26 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous day. 27 We created them and strengthened their joints; and whenever We wish, We can change their faces entirely. 28 Surely this is a reminder, so whoever pleases takes to his Lord a way. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He admits whoever He will into His grace and has prepared a painful punishment for the evil doers. 31
