It is We Who have sent down the Qur'an to thee by stages. 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 and remember the name of your Lord, morning and evening; 25 Prostrate before Him and glorify Him extensively during the night. 26 Those people [who are unmindful of God] aspire for immediate gains, and put behind them a Heavy Day. 27 We created them and made firm their make, and when We please We will bring in their place the likes of them by a change. 28 Surely this is a reminder, so whoever pleases takes to his Lord 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
