Al-Ahqaf (The Sandhills)

Surah 46 · Verse 11

And those who do not believe say regarding those who believe, “If the (Quran) were good they would not have preceded us in (accepting) it.” And when they do not receive guidance through it, then they say, “This is an old lie.”

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