Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 So be patient for the decision of your Lord and do not obey from among them a sinner or ungrateful [disbeliever]. 24 And remember thou the name of thy Lord in the morning 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 created them and fixed their bones and joints; and We could replace them when We like with others like them. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
