Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 So submit patiently to thy Lord's command, and obey not of them any guilty one or disbeliever. 24 And remember the Name of thy Lord at dawn and in the evening 25 and during some of the night, and prostrate thyself before Him, and extol His limitless glory throughout the long night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 27 [They will not admit to themselves that] it We who have created them and strengthened their make - and [that] if it be Our will We can replace them entirely with others of their kind. 28 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
