Al-Furqan · Ayah 4
وَقَالَ ٱلَّذِينَ كَفَرُوٓا۟ إِنْ هَٰذَآ إِلَّآ إِفْكٌ ٱفْتَرَىٰهُ وَأَعَانَهُۥ عَلَيْهِ قَوْمٌ ءَاخَرُونَ فَقَدْ جَآءُو ظُلْمًا وَزُورًا
And those who disbelieve say, "This [Qur’ān] is not except a falsehood he invented, and another people assisted him in it." But they have committed an injustice and a lie.
