It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that he said: "I came to the Prophet (peace and blessings be upon him) to offer him a camel of mine, and I saw that he (peace and blessings be upon him) prayed six rak'ahs of the forenoon (Duha) prayer."
This hadith is not narrated from Sayyiduna Jabir (may Allah be pleased with them both) except with this chain, and Mu'tamir (may Allah have mercy on him) is alone in narrating it.
