Suwayd bin Ghafalah narrates: I heard Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) say: The Prophet (peace and blessings be upon him) said: "In this Ummah there will be two arbiters; both of them will be astray, and whoever follows them will also be astray." The narrator says: I said: O Abu Musa! Take care that you are not one of the two.
Al-Tabarani recorded it and said: In my view this report is batil (false), because Ja'far bin Ali is an unknown shaykh who is not identified. (Allamah al-Haythami says:) I say: Its weakness comes only from Ali bin Abis al-Asadi, for he is matruk (abandoned).
