Surah Al-Ahqaf (46:11)
وَقَالَ ٱلَّذِينَ كَفَرُوا۟ لِلَّذِينَ ءَامَنُوا۟ لَوْ كَانَ خَيْرًا مَّا سَبَقُونَآ إِلَيْهِ وَإِذْ لَمْ يَهْتَدُوا۟ بِهِۦ فَسَيَقُولُونَ هَٰذَآ إِفْكٌ قَدِيمٌ
And those who have denied said to those who have believed, “If it had been good, they would not have preceded us to it.” And since they have not been guided by it, they will surely say, “This is an ancient fabrication.”
