A young man carrying his maternal uncle's name with his parents' consent

Q: Is it permissible for a young man to carry the name of his maternal uncle who adopted him since his birth with his parents' consent? Is he permitted to get married while carrying the name of his uncle? Is he considered a liar if he is asked about his name and answers the name of his uncle?

A: He is not permitted to carry the name of any one other than his father, for Allah (Exalted be He) states: ...nor has He made your adopted sons your real sons. That is but your saying with your mouths. But Allâh says the truth, and He guides to the (Right) Way. Call them (adopted sons) by (the names of) their fathers: that is more just with Allâh. But if you know not their father’s (names, call them) your brothers in faith and Mawâlîkum (your freed slaves). The Prophet (peace be upon him) stated: If anyone claims to be the son of a person other than his father or the servant of other than his own masters, there is upon him the curse of Allah, the angels and all the people. (Part No. 20; Page No. 378) (Reported by Muslim and others) May Allah grant us success. May peace and blessings be upon our Prophet, his family and Companions.
