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 Mention the Name of your Lord, mornings and evenings. 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 26 Indeed, these [disbelievers] love the immediate and leave behind them a grave Day. 27 It is We Who creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 28 This is indeed a Reminder, so that he who will, takes a path to his Lord. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
