(O Prophet), indeed We have revealed the Qur'an to you in portions. 23 Therefore be patient (O Muhammad SAW) and submit to the Command of your Lord (Allah, by doing your duty to Him and by conveying His Message to mankind), and obey neither a sinner nor a disbeliever among them. 24 And remember the name of your Lord morning and evening. 25 And during night, prostrate yourself to Him (i.e. the offering of Maghrib and 'Isha' prayers), and glorify Him a long night through (i.e. Tahajjud prayer). 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 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 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the 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
