If a person vows to perform Hajj and then performs the obligatory Hajj, does that suffice for the vow?

Question : Among the issues is if a person who owes the obligatory Hajj vows to perform Hajj, and then performs the Hajj of Islam, does that suffice for his obligation and his vow? There are two narrations on this.

Answer : The correct view in this detail is that if he vows to perform the obligatory Hajj, then his Hajj suffices for both the obligation and the vow, do you understand? Someone said, "I have a vow upon me to perform Hajj this year," and his intention was to perform the obligatory Hajj. If he performs it, it suffices for both. However, if he intends with the vow a separate Hajj, then the obligatory Hajj does not suffice for the vow.
