Quran 24:15 An-Nur, ayah 15 of 64

إِذْ تَلَقَّوْنَهُۥ بِأَلْسِنَتِكُمْ وَتَقُولُونَ بِأَفْوَاهِكُم مَّا لَيْسَ لَكُم بِهِۦ عِلْمٌ وَتَحْسَبُونَهُۥ هَيِّنًا وَهُوَ عِندَ ٱللَّهِ عَظِيمٌ ۝١٥

24:15 When ye welcomed it with your tongues, and uttered with your mouths that whereof ye had no knowledge, ye counted it a trifle. In the sight of Allah it is very great.
