Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 And mention the name of your Lord [in prayer] morning and evening 25 And prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 Surely men love what hastes away and forget the grievous day (ahead). 27 We have created them and have given them strength. Had We wanted, We could have replaced them with another people like them. 28 Verily this is an Exhortation; so let him who so will take a way to 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 to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
