Is there evidence in the saying of Allah the Exalted, “And to Madyan [We sent] their brother Shu‘ayb,” that it is permissible to address a disbeliever as “brother”?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: We have learned that it is not permissible for us to call Christians our brothers, so how do we understand the saying of Allah the Exalted:

Answer:
This refers to kinship. This is in terms of kinship, because Allah sends the Messenger from the same tribe or nation in order to make things clear to them. And We did not send any Messenger except in the language of his people to make things clear to them. If someone they did not know came to them, they would not accept from him.
But if he came to them as their cousin and their brother in kinship, and they knew his upbringing and knew his truthfulness and trustworthiness, they would have no excuse for not accepting what he brought.
So Allah sends in every generation and in every nation a Messenger from among them. Yes, they know him. Yes.
