Surat Yūnus - سورة يونس

وَإِذَا تُتْلَىٰ عَلَيْهِمْ آيَاتُنَا بَيِّنَاتٍ ۙ قَالَ الَّذِينَ لَا يَرْجُونَ لِقَاءَنَا ائْتِ بِقُرْآنٍ غَيْرِ هَٰذَا أَوْ بَدِّلْهُ ۚ قُلْ مَا يَكُونُ لِي أَنْ أُبَدِّلَهُ مِن تِلْقَاءِ نَفْسِي ۖ إِنْ أَتَّبِعُ إِلَّا مَا يُوحَىٰ إِلَيَّ ۖ إِنِّي أَخَافُ إِنْ عَصَيْتُ رَبِّي عَذَابَ يَوْمٍ عَظِيمٍ

Muhsin Khan: And when Our Clear Verses are recited unto them, those who hope not for their meeting with Us, say: Bring us a Quran other than this, or change it."Say (O Muhammad SAW): "It is not for me to change it on my own accord; I only follow that which is revealed unto me. Verily, I fear if I were to disobey my Lord, the torment of the Great Day (i.e. the Day of Resurrection)."
