Vowing to take her son for Hajj before attaining the age of puberty but never doing so

Q 1: My mother vowed to make me perform Hajj before I reach the age of puberty, because I was chronically ill. She said, "If my son recovers, I will make him perform Hajj before he reaches the age of puberty." However, I reached the age of puberty and she did not make me perform Hajj. Please advise concerning what she should do, may Allah reward you.

A: She should fulfill her vow and perform Hajj with you, even if you reached the age of puberty, as this vow is one of obedience, and the Prophet (peace be upon him) said, Whoever vows to do an act of obedience to Allah should do so; and whoever vows to disobey Allah should not do so. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
