It is We Who have sent down the Qur'an to thee by stages. 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 and remember the name of your Lord, morning and evening; 25 and prostrate yourself before Him at night, and extol His Glory during the long watches of the night. 26 These people (disbelievers) love the worldly life and neglect the terrifying day which will come. 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 Indeed, this is a reminder, so he who wills may take to his Lord a way. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
