Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 And, remember the Name of your Lord at the dawn and in the evening; 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Those people [who are unmindful of God] aspire for immediate gains, and put behind them a Heavy Day. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 And what will you wish, except if Allah wills; indeed Allah is All Knowing, Wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
