Al-Furqan - 25:4

وَقَالَ الَّذِينَ كَفَرُوا إِنْ هَذَا إِلَّا إِفْكٌ افْتَرَاهُ وَأَعَانَهُ عَلَيْهِ قَوْمٌ آخَرُونَ فَقَدْ جَاؤُوا ظُلْمًا وَزُورًا
[25:4]
And those who disbelieve say: This is nothing but a lie which he has forged, and other people have helped him at it; so indeed they have done injustice and (uttered) a falsehood.
But the misbelievers say: "Naught is this but a lie which he has forged, and others have helped him at it." In truth it is they who have put forward an iniquity and a falsehood.
Those who disbelieve say: This is naught but a lie that he hath invented, and other folk have helped him with it, so that they have produced a slander and a lie.
