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 And during part of the night adore Him, and give glory to Him (a) long (part of the) night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 27 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 Surely this is a reminder, so whoever pleases takes to his Lord a way. 29 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
