Qur'ān 46:11 · Al-Ahqaf (الأحقاف)

وَقَالَ ٱلَّذِينَ كَفَرُوا۟ لِلَّذِينَ ءَامَنُوا۟ لَوْ كَانَ خَيْرًۭا مَّا سَبَقُونَآ إِلَيْهِ ۚ وَإِذْ لَمْ يَهْتَدُوا۟ بِهِۦ فَسَيَقُولُونَ هَـٰذَآ إِفْكٌۭ قَدِيمٌۭ

And those who disbelieve say of those who believe, "If it had [truly] been good, they would not have preceded us to it." And when they are not guided by it, they will say, "This is an ancient falsehood."
