It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, Allah Almighty has placed this matter (caliphate and authority) among you, and you are its custodians, and it will remain among you as long as you do not commit deeds because of which it is taken away from you. Then when you do that, Allah Almighty will set over you the worst of His creation, and they will strip you bare (flaying your skin and peeling away all you have) just as a branch is stripped of its bark."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from al-A'mash (may Allah have mercy on him) except Abu Awanah and Abu Yahya al-Himmani. Abu Malik Kathir bin Yahya is alone in narrating it from Abu Awanah, and Abu Kurayb is alone in narrating it from Abu Yahya al-Himmani."
In the Dar al-Haramayn edition it appears like this (al-Qasim bin Ubaydullah bin Abdullah), and probably the correct form is (al-Qasim from Ubaydullah bin Abdullah).
