It is We Who have sent down the Qur'an to thee by stages. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And remember the Name of thy Lord at dawn and in the evening 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Indeed, these [disbelievers] love the immediate and leave behind them a grave Day. 27 It is We Who creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 28 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and Wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
