It is We Who have sent down the Qur'an to thee by stages. 23 So be patient for the decision of your Lord and do not obey from among them a sinner or ungrateful [disbeliever]. 24 And mention the name of your Lord [in prayer] morning and evening 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Indeed, these [disbelievers] love the immediate and leave behind them a grave Day. 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and 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
