Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 Mention the Name of your Lord, mornings and evenings. 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 These people (disbelievers) love the worldly life and neglect the terrifying day which will come. 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 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He admits unto His grace everyone who wills [to be admitted]; but as for the evildoers - for them has He readied grievous suffering [in the life to come]. 31
