Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 23 So submit patiently to thy Lord's command, and obey not of them any guilty one or disbeliever. 24 And remember thou the name of thy Lord in the morning and in the evening. 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 Indeed, this is a reminder, so he who wills may take to his Lord a way. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
