It is We Who have sent down the Qur'an to thee by stages. 23 Await, then, in all patience thy Sustainer's judgment, and pay no heed to any of them, who is a wilful sinner or an ingrate; 24 Remember the name of thy Lord at morn and 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 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous day. 27 We created them and made firm their make, and when We please We will bring in their place the likes of them by a change. 28 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 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
