It is We Who have sent down the Qur'an to thee by stages. 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 during the night - worship Him; and hallow Him the livelong night. 26 Verily those love the herein, and leave in front of them a heavy day. 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 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 And what will you wish, except if Allah wills; indeed Allah is All Knowing, 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
