We have revealed the Qur'an to you gradually; 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 your Lord at the dawn and in the evening; 25 Prostrate before Him and glorify Him extensively during the night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
