It is known that Ali is the first person to convert to Islam, however some dispute this arguing he was only 12 years old at the time he embraced Islam. Ali had four children with Fatimah: Hasan ibn Ali, Husayn ibn Ali, Zaynab bint Ali and Umm Kulthum bint Ali. His other well-known sons were al-Abbas ibn Ali, born to Fatima binte Hizam (Um al-Banin), and Muhammad ibn al-Hanafiyyah. Muhammad ibn al-Hanafiyyah was Ali's son from another wife from the Bani Hanifa tribe of central Arabia named Khawlah bint Ja'far, whom Ali had married after Fatimah's death.
