(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 Meditate upon the name of your Lord morning and evening; 25 And prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 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 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
