It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the last thing the Messenger of Allah (peace and blessings be upon him) said was: "Succeed me well regarding my family (Ahl al-Bayt) (that is, take care of them after me)."
Imam al-Tabarani (may Allah have mercy on him) said: "Only al-Zubayr bin Habib narrated this hadith from Asim bin Ubaydullah, and Ya'qub bin Humayd is alone in narrating it."
