The ruling on one who claims kinship with his uncle to obtain the nationality of a country where his children are settled

Question:
I ask Allah to do you good. Your Eminence, father, the questioner asks: What is the ruling on one who goes to one of the neighboring countries and claims kinship with one of his relatives, such as his uncle or his cousin, and thereby obtains the nationality of that country, even though he is not called by any name other than his real name, but he did so in order to obtain the nationality and the job and salary that come with it? If one does this, what is required of him, especially since his sons are now employed and settled in their homes?

Answer:
This is not permissible. This is a long question, so that we may tell him what contradicts it. No, this is not permissible. First, it is lying, and lying is not permissible. Second, it is deception, and deception is not permissible. Third, he claimed kinship with someone other than his father, and this is a major sin. The Prophet (peace and blessings be upon him) cursed the one who claims kinship with someone other than his father. He must repent to Allah, return matters to their original state, rectify his situation, and stop lying. Yes.
