Ja'far bin Muhammad (may Allah have mercy on him) narrates from his father (may Allah have mercy on him) that Safwan (may Allah be pleased with him) lent the Messenger of Allah (peace and blessings be upon him) weapons, and they were 80 coats of mail. He said to him (peace and blessings be upon him): As a loan or by force? The Messenger of Allah (peace and blessings be upon him) said: "It is a loan; we will return them."
Some of these reports, even if mursal, are strengthened by their supporting reports together with the connected (mawsul) narrations mentioned earlier, and Allah knows best.
