It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "The worst of those killed is one who is killed between two ranks, one of which is seeking kingship."
No one narrated this hadith from Muhammad bin al-Munkadir (may Allah have mercy on him) except Usamah bin Zayd (may Allah have mercy on him), and no one from Usamah (may Allah have mercy on him) except Ibn Wahb (may Allah have mercy on him), while Abd al-Awwal al-Mu'allim (may Allah have mercy on him) is alone in narrating it.
