The vow to refrain from riding a mount and its resemblance to the practices of the pre-Islamic age of ignorance

Question:
May Allah reward you. If a person vows not to ride his mount, for example, resembling the practice of the people of the pre-Islamic age of ignorance? And is this shirk (associating partners with Allah) because the vow of prohibition is intended to draw near to Allah?

Answer:
Yes. If he forbids himself from riding, this contains a resemblance to the prohibition of lawful things in the religion of the pre-Islamic age of ignorance. The scholars differed on whether a person who vows to perform Hajj on foot, as an act of worship to Allah the Exalted, is required to fulfill this vow. He is not required to do so; rather, he should ride and expiate for his vow, as the Prophet (peace and blessings be upon him) issued a ruling for a woman who vowed to perform Hajj on foot. Likewise, he issued a ruling for a man who vowed to perform Hajj on foot, telling him to ride and expiate for his vow with the expiation for an oath. Yes.
