It is narrated from Muhammad bin Umar that the lineage of Abu Qatadah is: Abu Qatadah bin Rib'i bin Baldamah bin Khunas bin Sinan bin Ubayd bin Adi bin Ghanm bin Ka'b bin Salimah bin Sa'd bin Ali bin Asad bin Saridah bin Tazid bin Jusham bin al-Khazraj. There is a difference of opinion about his name: Muhammad bin Ishaq used to say that his name was al-Harith bin Rib'i; Abdullah bin Muhammad bin Umarah said that his name was al-Nu'man bin Rib'i; and some said Amr bin Rib'i. He took part in the battles of Uhud and al-Khandaq and all the engagements after them alongside the Messenger of Allah (peace and blessings be upon him).
