It is narrated from Sayyiduna Mahmood bin Labeed (may Allah be pleased with him) that on the day of Uhud, the swords of the Muslims struck Sayyiduna Iman (may Allah be pleased with him), while they did not recognize him, so they killed him. Then the Noble Prophet (peace and blessings be upon him) wished to pay his blood money, but Sayyiduna Hudhaifah (may Allah be pleased with him) gave that blood money as charity to the Muslims.
