The ruling on a woman who vowed to perform Hajj and her husband prevented her

This is a letter received from the sender (Raqiyyah M. 'A) complaining about her husband in this letter. She says: In the name of Allah, the Most Gracious, the Most Merciful. To His Eminence Shaykh 'Abd al-'Aziz ibn Baz, may Allah grant him understanding, amen, and prolong his life and make Paradise his abode, amen. Peace be upon you and Allah's mercy and blessings. After that: His Eminence the Shaykh, I am complaining about my husband, not objecting to him, but to establish the truth. May Allah guide him, he prevented me from performing Hajj. This is because I vowed to perform Hajj this year, and he said: "A woman should not vow anything without informing her husband beforehand." Is he allowed to prevent me from fulfilling this vow? Please answer us, and may Allah guide you to what He loves and is pleased with?
Answer: This is also a question of importance and value. We will postpone it to another session so that I may reflect on the words of the scholars regarding this, and look into the words of the scholars, and whether it is obligatory for him to authorize her or if there is no objection to delaying it. This is a matter for consideration. As for the vow, there is no doubt that it is a right, but it is not recommended for her to make a vow. However, since it has occurred, in any case, as long as the vow has been made, it is necessary to look into the answer, if Allah wills, in another session. We will look into the matter, O questioner! We will look into the subject, if Allah wills, and then answer you, if Allah wills, through the program "Light on the Path," by the power of Allah. We will answer you with what we see as being in accordance with the Shari'ah in this matter, so that your husband knows, and so that you know what is obligatory by the Shari'ah in this position, according to what we know from the law of Allah, after looking into and reflecting on the subject, if Allah wills.
