Umm al-Husayn (Hasan) the mother of al-Husayn (Hasan) Ibn Musa Ibn Ja'far ('a) was one of the wives of Imam al-Kazim ('a). Nothing is known about her biography. Her name is known due to a tradition that has been transmitted by Shaykh al-Kulayni, al-Saduq, and Shaykh al-Tusi that will be quoted in the section on traditions below.

In the books of genealogy, a son of Imam al-Kazim by the name of al-Husayn (or Hasan) has been mentioned1 but there is no mention of a daughter by the name of Umm al-Husayn. If some of the books about the transmitters of traditions mention the name Umm al-Husayn Bint Musa Ibn Ja'far, it is probably incorrect.2

Her Merits

Imam al-Sadiq ('a) told his mother, al-Khansa' the wife of Sa'd, about her: "Even if Allah has given you nothing save your daughter Umm al-Husayn, it is still that He has actually given you very much welfare."3

She has related traditions from Imam Musa Ibn Ja'far, and al-Husayn (Hasan) Ibn Musa Ibn Ja'far has related traditions from her.

Shaykh al-Kulayni and Shaykh al-Tusi quote Ahmad Ibn Muhammad as relating from al-Husayn Ibn Musa4 as transmitting that his mother and Umm Ahmad Bint Musa said, "We were traveling to Baghdad through the desert with Abu al-Hasan ('a). He said, 'Today is Thursday. But, take the ritual ablution today instead of tomorrow, because tomorrow we will find very little water.' So, we took the ablution on Thursday instead of FRidhay."5
