Ya-Sin 36:14

Ith arsalna ilayhimu ithnaynifakaththaboohuma faAAazzazna bithalithinfaqaloo inna ilaykum mursaloon

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."

when We sent to them two (apostles), and they rejected both of them, so We confirmed them with a third one. So they said, “We are sent to you.”
