Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 So wait patiently for the command of your Lord and do not yield to any sinful or disbelieving person among them (people). 24 And, remember the Name of your Lord at the dawn and in the 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 those love the herein, and leave in front of them a heavy day. 27 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 28 Surely this is a reminder, so whoever pleases takes to his Lord a way. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 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
