Surah Yasin, ayah 14

36:14

إِذۡ أَرۡسَلۡنَآ إِلَيۡهِمُ ٱثۡنَيۡنِ فَكَذَّبُوهُمَا فَعَزَّزۡنَا بِثَالِثٖ فَقَالُوٓاْ إِنَّآ إِلَيۡكُم مُّرۡسَلُونَ ١٤

Idh arsalnā ilayhimuthnayni fakaddhabūhumā fa'azzaznā bithālithin faqālū innā ilaykum mursalūn

When We sent to them two but they denied them, so We strengthened [them] with a third, and they said, "Indeed, we are messengers to you."
