AL AHQAAF — Ayat 11

وَقَالَ الَّذِينَ كَفَرُوا لِلَّذِينَ آمَنُوا لَوْ كَانَ خَيْرًا مَّا سَبَقُونَا إِلَيْهِ وَإِذْ لَمْ يَهْتَدُوا بِهِ فَسَيَقُولُونَ هَذَا إِفْكٌ قَدِيمٌ

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."
