From him, from Muhammad ibn Al-Husayn, from Muhassin ibn Ahmad, from Muhammad ibn Hubab, from Yunus, from Abu Abdullah عليه السلام: Imam عليه السلام said: "Indeed, (Sayyida) Fatimah صلى الله عليه وعلى آله وسلم, peace be upon her, used to visit the graves of the martyrs every Saturday morning. She would go to the grave of Hamzah عليه السلام, pray for mercy upon him, and seek forgiveness for him."
