As Abû ʿAbd Allâh al-Ḥusayn, son of ʿAlî and Fâṭima and grandson of Muḥammad, moved inexorably towards death on the field of Karbalâʾ, his sister Zaynab was drawn ever closer to the centre of the family of Muḥammad, the ‘people of the house’ (ahl al-bayt). There she would remain for a few historic days, challenging the wickedness of the Islamic leadership, defending the actions of her brother, initiating the commemorative rituals, protecting and nurturing the new Imâm, al-Ḥusayn’s son ʿAlî b. al-Ḥusayn b. ʿAlî b. Abî Ṭâlib, until he could take his rightful place. This is her story.
