It is We Who have sent down the Qur'an to thee by stages. 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 Mention the Name of your Lord, mornings and evenings. 25 and in the night prostrate to Him; and exalt Him for a long night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He will admit to His Mercy whom He will and as for the Zalimun, (polytheists, wrong-doers, etc.) He has prepared a painful torment. 31
