ʿAbd al-Ghanī composed a work on this topic, followed by al-Khaṭīb and others. I have abridged al-Khaṭīb’s book, refined it, arranged it in an orderly fashion, and added valuable material to it. A person whose name is left vague may often be identified when he appears explicitly named in other narrations.
