﴿وَإِذَا تُتْلَىٰ عَلَيْهِمْ آيَاتُنَا بَيِّنَاتٍ ۙ قَالَ الَّذِينَ لَا يَرْجُونَ لِقَاءَنَا ائْتِ بِقُرْآنٍ غَيْرِ هَٰذَا أَوْ بَدِّلْهُ ۚ قُلْ مَا يَكُونُ لِي أَنْ أُبَدِّلَهُ مِنْ تِلْقَاءِ نَفْسِي ۖ إِنْ أَتَّبِعُ إِلَّا مَا يُوحَىٰ إِلَيَّ ۖ إِنِّي أَخَافُ إِنْ عَصَيْتُ رَبِّي عَذَابَ يَوْمٍ عَظِيمٍ﴾
15. And when Our clear Verses are recited unto them, those who hope not for their meeting with Us, say: "Bring us a Qur’ân other than this, or change it." Say (O Muhammad ﷺ): "It is not for me to change it on my own accord; I only follow that which is revealed unto me. Verily, I fear the torment of the Great Day (i.e. the Day of Resurrection) if I were to disobey my Lord."
