Jamilah was the wife of Aws bin Samit. Aws was a man afflicted with bouts of madness, and whenever his condition worsened he would pronounce the zihar formula against his wife. So Allah revealed concerning him the expiation for zihar.
أن جميلة كانت امرأة أوس بن الصامت، وكان أوس امرءا به لمم، فإذا اشتد لممه ظاهر من امرأته، فأنزل الله فيه كفارة الظهار.
Abu Dawud (2220), Hakim (2/481), and Bayhaqi (7/382) all narrated it via Muhammad bin Fadl, Abu Numan, who said, "Hammad bin Salama narrated to us, from Hisham bin Urwa, from his father, from Ayesha," and then he related it.Muhammad bin Fadl, nicknamed Arim, was reliable, but his memory became confused toward the end of his life, and this confusion became firmly established in the year 216 AH. Harun bin Abdullah related from him here, as found in Abu Dawud, as did Ali bin Hasan Hilali, as found in Hakim and Bayhaqi. Hakim said, "Sahih according to the criterion of Muslim."There is disagreement regarding this hadith going back to Hammad bin Salama. Arim related it from him as connected, and Sulayman bin Harb agreed with him on this, as found in Bayhaqi's Marifah (5/28). Sulayman bin Harb said, "If Abu Numan agrees with me, I do not care who disagrees with me." Nasai quoted this in Sunan al-Kubra. Assad bin Musa also agreed with him, as found in Tabari's tafsir.Musa bin Ismail Tabuzaki disagreed with them, relating it from Hammad bin Salama, from Hisham bin Urwa, that Jumaylah... and so on, narrating it in this way as mursal. Abu Dawud related this (2291).The ruling goes to those who connected the chain, due to their greater number.
