Ruling on attributing oneself to someone other than one's father

Question:
Attributing oneself to the grandfather?

Answer:
It is not permissible; one must attribute oneself to his father. Attributing oneself to the grandfather is permissible, but one must not intentionally leave out the father. Otherwise, if he attributes himself to the grandfather because it is the more well-known attribution, like the saying of the Prophet (peace and blessings be upon him): He is his grandfather. So if he attributes himself to him because of his fame and says, "I am from his descendants," he is truthful; he is from his descendants. But in nationalities and other non-national matters, no, the father must be listed; because he may have brothers, he may have paternal uncles, so that he is known.
Q: Is it permissible to attribute oneself to one's paternal uncle on the grounds that he is the one who raised him?
The Shaykh: No, he does not attribute himself to him; he attributes himself to his father only. He does not attribute himself to his paternal uncle or his cousin.
Q: ... Now, some of the young ones say, for example, "My father is so-and-so and so-and-so," using the name of his father and his grandfather, applying the title "father" to his grandfather.
The Shaykh: It does not contradict, but in nationality, residence, and official matters, the situation must be corrected to his father. As for general attribution, there is no harm, just as the Prophet (peace and blessings be upon him) attributed himself to 'Abd al-Muttalib , and just as it is said: "The Arabs are the sons of Isma'il," an attribution to their most senior grandfather, and "The Jews are the sons of Ishaq," their most senior grandfather is Ishaq; this is not a problem. But in official matters, the father must be established.
Q: Can a sister's son attribute himself to his maternal uncles?
The Shaykh: But he does not attribute himself to them in official matters. He says, "My maternal uncles are the family of so-and-so," "My maternal uncles are from Mutayr," "My maternal uncles are from Banu Hashim," but he does not attribute himself to them by saying, "I am the son of so-and-so the Hashimi," and that would be a lie.
Q: May Allah reward you. What about someone who dislikes his father's name and attributes himself to his grandfather because the name is strange?
The Shaykh: Even so, in nationality, residence, and the like, he must specify his father. As for in general, that he is from the sons of the well-known grandfather; there is no harm. This is found among the Arabs, who attribute themselves to their well-known fathers. But in nationalities that carry legal rulings, it must be to his father, and the grandfather is the father.
Q: Some countries name them: "The wife of so-and-so," meaning by the name of the husband?
The Shaykh: "The wife of so-and-so," this is an easy convention. "The wife of so-and-so" means the wife of so-and-so.
Q: No, does she belong to him?
The Shaykh: No, she belongs to her father. This is a mistake. So-and-so, the daughter of so-and-so, the wife of so-and-so, that does not contradict.
Q: What is the ruling on changing the names of families, not tribes, changing only the family name?
The Shaykh: If he says: "I am from Quraysh" or "from Banu Hashim" or "from Mutayr" or from..., there is no harm. But he does not attribute himself to anyone other than his father.
