The majority of Shi'a's are in agreement that Umm Kulthum, the daughter of the Ali, was not married to Umar.[8][9][10][11][12][13][14][15][16][17][18] One narration concerning the marriage is, A hadith attributed to Ja'far al-Sadiq reports:[citation needed] When `Omer sought the hand of Umm Kultham for marriage, Ali (A.S.) said, `But she is only a child,’ `Omer said to al-`Abbas, ‘I sought the hand of the daughter of your nephew, and he turned me down. By Allah, I shall damage the well of Zamzam, and I shall leave nothing precious belonging to you except that I ruin it, and I shall get two witnesses to testify that he stole, and I shall cut off his right hand.’ Al-`Abbas came and informed Ali (A.S.) (of what `Omer had said), asking him to let him take care of that matter, which he did Shi'as tend to view this as Sahih and have included it in Furu al-Kafi.[19].
