وَاِذَا تُتۡلٰى عَلَيۡهِمۡ اٰيَاتُنَا بَيِّنٰتٍۙ قَالَ الَّذِيۡنَ لَا يَرۡجُوۡنَ لِقَآءَنَا ائۡتِ بِقُرۡاٰنٍ غَيۡرِ هٰذَاۤ اَوۡ بَدِّلۡهُ ؕ قُلۡ مَا يَكُوۡنُ لِىۡۤ اَنۡ اُبَدِّلَهٗ مِنۡ تِلۡقَآئِ نَفۡسِىۡۚ اِنۡ اَتَّبِعُ اِلَّا مَا يُوۡحٰىۤ اِلَىَّ ۚ اِنِّىۡۤ اَخَافُ اِنۡ عَصَيۡتُ رَبِّىۡ عَذَابَ يَوۡمٍ عَظِيۡمٍ
And when Our enlightening Revelations are recited to them, those who do not believe in meeting Us say: ‘Bring us a Qur’an different from this one or alter it.’ (O Glorious Messenger,) say: ‘I have no right to modify it of my own accord. I follow only (that) which is revealed to me. I indeed fear the chastisement of the Mighty Day if I go against my Lord.’
