17:105And with the truth We have sent it [i.e., the Qur’ān] down, and with the truth it has descended. And We have not sent you, [O Muḥammad], except as a bringer of good tidings and a warner.

17:106And [it is] a Qur’ān which We have separated [by intervals] that you might recite it to the people over a prolonged period. And We have sent it down progressively.

17:107Say, "Believe in it or do not believe." Indeed, those who were given knowledge before it1 - when it is recited to them, they fall upon their faces in prostration,

17:108And they say, "Exalted is our Lord! Indeed, the promise of our Lord has been fulfilled."

17:109And they fall upon their faces weeping, and it [i.e., the Qur’ān] increases them in humble submission.

17:110Say, "Call upon Allāh or call upon the Most Merciful [ar-Raḥmān]. Whichever [name] you call - to Him belong the best names." And do not recite [too] loudly in your prayer or [too] quietly but seek between that an [intermediate] way.

17:111And say, "Praise to Allāh, who has not taken a son and has had no partner in [His] dominion and has no [need of a] protector out of weakness; and glorify Him with [great] glorification."

18:1[All] praise is [due] to Allāh, who has sent down upon His Servant [Muḥammad (ﷺ)] the Book and has not made therein any deviance.1

18:2[He has made it] straight, to warn of severe punishment from Him and to give good tidings to the believers who do righteous deeds that they will have a good reward [i.e., Paradise].

18:3In which they will remain forever

18:4And to warn those who say, "Allāh has taken a son".
