إِذْ تَلَقَّوْنَهُ بِأَلْسِنَتِكُمْ وَتَقُولُونَ بِأَفْوَاهِكُم مَّا لَيْسَ لَكُم بِهِ عِلْمٌ وَتَحْسَبُونَهُ هَيِّنًا وَهُوَ عِندَ اللَّهِ عَظِيمٌ (15)
(24:15) (Just think how erroneous you were,) when you passed this lie on from one tongue to the other and uttered with your mouths that of which you had no knowledge. You took it as a trifling matter whereas it was a grave offence in the sight of Allah.
