(The Messenger’s Language)
We did not send any messenger except (to preach) in the tongue of his people, in order to clarify things for them. God then sends astray whomever He wills, and guides whomever He wills. He is the Almighty, the Most Wise.
وَما أَرسَلنا مِن رَسولٍ إِلّا بِلِسانِ قَومِهِ لِيُبَيِّنَ لَهُم فَيُضِلُّ اللَّهُ مَن يَشاءُ وَيَهدى مَن يَشاءُ وَهُوَ العَزيزُ الحَكيمُ
