A woman entering ihram for Hajj without her husband's permission

It is narrated from Matar that a woman asked her husband's permission to perform Hajj, but her husband did not permit her. Then she asked her husband's permission to go out visiting, and he permitted her. Then the woman wrapped her white garments around herself and began reciting the talbiyah for Hajj aloud. The people came to al-Hasan and asked him. Al-Hasan said: The foolish woman! She has no right to that.

Matar said: Qatadah was asked, and he said: She is in the state of ihram.

Matar said: Then I went to Makkah and asked al-Hakam bin Utaybah, and he said: She is in the state of ihram.

Matar said: Then I asked a man to put the question to Ata bin Abi Rabah, and he said: No, and certainly not (lit. may no eye be delighted by it); she has no right to that.

Ibrahim said: When the Hajj is obligatory and the woman has a mahram with her, then there is no harm in her setting out for Hajj without asking her husband's permission.

Al-Hasan said regarding a woman who has not performed Hajj: she should ask her husband's permission; if her husband permits her, that is better in my view, and if her husband does not permit her, she should set out for Hajj with one of her mahrams, because Hajj is one of the obligations of Allah Almighty, and in it obedience is owed to no one (except Allah Almighty).
