Some verses in the Qur'an are associated with Fatimah and her household by classical exegetes, although she is not mentioned by name. According to J. D. McAuliffe, two of the most important verses include the verse of purification, which is the 33rd ayah in Surah al-Ahzab, and the 61st ayah in Surah Al-i-Imran. In the first verse, the phrase "people of the house" ("ahl al-bayt") is ordinarily understood to consist of Muhammad, Fatimah, her husband Ali and their two sons (al-Tabari in his exegesis also mentions a tradition that interprets "people of the house" as Muhammad's wives; for Ibn al-Jawzi, the order of these options is reversed). The second verse refers to an episode in which Muhammad proposed an ordeal of mutual adjuration ("Mubahala") to a delegation of Christians. Fatimah, according to the "occasion for the revelation" of this verse, was among those offered by Muhammad as witnesses and guarantors.
