﴿ 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 manifest bayyināt is a circumstantial qualifier verses from the Qur’ān are recited to them those who do not expect to encounter Us those who do not fear the Resurrection say ‘Bring a Qur’ān other than this one in which our gods are not denigrated or change it’ of your own accord. Say to them ‘It is not for me to change it of my own accord. I only follow that which is revealed to me. Truly I fear if I should disobey my Lord by changing it the chastisement of a dreadful day’ that is the Day of Resurrection.
