﴿ وَإِذَا تُتْلَىٰ عَلَيْهِمْ ءَايَاتُنَا بَيِّنَٰتٍۢ ۙ قَالَ ٱلَّذِينَ لَا يَرْجُونَ لِقَآءَنَا ٱئْتِ بِقُرْءَانٍ غَيْرِ هَٰذَآ أَوْ بَدِّلْهُ ۚ قُلْ مَا يَكُونُ لِىٓ أَنْ أُبَدِّلَهُۥ مِن تِلْقَآئِ نَفْسِىٓ ۖ إِنْ أَتَّبِعُ إِلَّا مَا يُوحَىٰٓ إِلَىَّ ۖ إِنِّىٓ أَخَافُ إِنْ عَصَيْتُ رَبِّى عَذَابَ يَوْمٍ عَظِيمٍۢ ﴾

“AND [thus it is:] whenever Our messages are conveyed unto them in all their clarity, those who do not believe that they are destined to meet Us [are wont to] say, "Bring us a discourse other than this, or alter this one.” Say [O Prophet]: "It is not conceivable that I should alter it of my own volition; I only follow what is revealed to me. Behold, I would dread, were I [thus] to rebel against my Sustainer, the suffering [which would befall me] on that awesome Day [of Judgment]!"”

(And when Our clear revelations) detailing commands and prohibitions (are recited unto them) are recited by you unto the scoffers: al-Walid Ibn al-Mughirah and his host (they who look not for the meeting with Us) those who do not fear resurrection after death while at the same time scoff (say: Bring) O Muhammad (a Lecture other than this, or change it) putting the verses of mercy in the place of the verses of chastisement and the verses of chastisement in place of the verses of mercy. (Say) to them, O Muhammad: (It is not for me) it is not permissible for me (to change it of my own accord. I only follow that which is inspired in me) I do not say or do except that which is revealed to me in the Qur'an. (Lo! If I disobey my Lord) by changing the revelation (I fear) I know (the retribution of an awful Day) a severe Day.
