It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Allah Almighty will fill your hands with non-Arabs (that is, they will come under your control in great numbers); then they will become like lions who do not flee; they will strike your necks and take your fay' (spoils)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Layth (may Allah have mercy on him) except Abdullah bin Abd al-Quddus, and this hadith is not narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) except with this chain."
