And whatever is narrated regarding the will of Amir Al-Muʾminin, peace be upon him, to his son Muhammad ibn Al-Hanafiyyah - may Allah (swt) be pleased with him - I have narrated it from my father - may Allah (swt) be pleased with him - from Ali ibn Ibrahim ibn Hashim, from his father, from Hammad ibn ʿIsa, from someone who mentioned it from Abu Abdillah, peace be upon him. Most people make an error in this chain of transmission by replacing Hammad ibn ʿIsa with Hammad ibn Uthman, whereas Ibrahim ibn Hashim did not meet Hammad ibn Uthman; rather, he met Hammad ibn ʿIsa and narrated from him.
