وَاِذَا تُتْلٰى عَلَيْہِمْ اٰيَاتُنَا بَيِّنٰتٍ۰ۙ قَالَ الَّذِيْنَ لَا يَرْجُوْنَ لِقَاۗءَنَا ائْتِ بِقُرْاٰنٍ غَيْرِ ھٰذَاۗ اَوْ بَدِّلْہُ۰ۭ قُلْ مَا يَكُوْنُ لِيْۗ اَنْ اُبَدِّلَہٗ مِنْ تِلْقَاۗيِ نَفْسِيْ۰ۚ اِنْ اَتَّبِـــعُ اِلَّا مَا يُوْحٰۗى اِلَيَّ۰ۚ اِنِّىْۗ اَخَافُ اِنْ عَصَيْتُ رَبِّيْ عَذَابَ يَوْمٍ عَظِيْمٍ۱۵
