(O Prophet), indeed We have revealed the Qur'an to you in portions. 23 So wait patiently for the command of your Lord and do not yield to any sinful or disbelieving person among them (people). 24 Mention the Name of your Lord, mornings and evenings. 25 And during the night - worship Him; and hallow Him the livelong night. 26 Those people [who are unmindful of God] aspire for immediate gains, and put behind them a Heavy 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 Surely this is a reminder, so whoever pleases takes to his Lord a way. 29 And you do not please except that Allah please, surely Allah is Knowing, Wise; 30 He admits whoever He will into His grace and has prepared a painful punishment for the evil doers. 31
