Ya-Sin - 36:14

إِذْ أَرْسَلْنَا إِلَيْهِمُ اثْنَيْنِ فَكَذَّبُوهُمَا فَعَزَّزْنَا بِثَالِثٍ فَقَالُوا إِنَّا إِلَيْكُم مُّرْسَلُونَ
[36:14]
When We sent to them two, they rejected both of them, then We strengthened (them) with a third, so they said: Surely we are messengers to you.
When We (first) sent to them two messengers, they rejected them: But We strengthened them with a third: they said, "Truly, we have been sent on a mission to you."
When We sent unto them twain, and they denied them both, so We reinforced them with a third, and they said: Lo! we have been sent unto you.
