What is the ruling on performing Hajj on behalf of a boy who died before reaching puberty?

Question:
This questioner says: She is a daughter whom Allah took, and she was thirteen years old. Does she have a limit?

Answer:
She had reached puberty by the growth of hair around the private parts, or by menstruation, or by discharge. Discharge means wet dreams, or thinking. This makes her accountable. If she has money, if she has wealth, Hajj is performed on her behalf. If she does not have the obligation of Hajj, Hajj is performed for the one who is able. But if she has money, Hajj is performed on her behalf. As for if she was not accountable, if she was not accountable by age at thirteen, the age is fifteen, but she may be accountable by menstruation. She may menstruate at twelve, eleven, or ten. She may be accountable by hair, a hair growing at the private parts. She may be accountable by the discharge of semen in thinking, in intercourse, in thinking about men. She may discharge. The man is also the same; he may reach puberty by discharge, in wet dreams, and otherwise, by hair, and by completing fifteen years. The woman is also the same by completing fifteen years, by the discharge of semen from a wet dream or desire, and by the growth of hair. The woman has a fourth matter added, which is menstruation. If Hajj is performed for a minor, there is no harm. If Hajj is performed as a voluntary act, there is no harm. If her guardian performs Hajj for her, or if a minor dies and Hajj is performed as a voluntary act, there is no harm. This is a voluntary Hajj, just as Hajj is performed for one who is not able. If a person dies and he was not able to perform Hajj, his children and others perform Hajj for him as a voluntary act; because the obligatory Hajj is not required. He died and the obligatory Hajj was not required.
