(O Prophet), indeed We have revealed the Qur'an to you in portions. 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 And mention the name of your Lord [in prayer] morning and evening 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 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 will not desire except as God wills. Verily He is all-knowing and all-wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
