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."
The Saheeh International Quran Translation
إِذْ أَرْسَلْنَآ إِلَيْهِمُ ٱثْنَيْنِ فَكَذَّبُوهُمَا فَعَزَّزْنَا بِثَالِثٍ فَقَالُوٓا۟ إِنَّآ إِلَيْكُم مُّرْسَلُونَWhen 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."
