It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that a man in the state of ihram was thrown by his mount and killed, so the Messenger of Allah (peace and blessings be upon him) said: "Wash him with water and lote-tree leaves, shroud him in his two garments, and do not bring perfume near him, for he will be raised on the Day of Resurrection reciting the Talbiyah, or he said: with his hair matted (as in ihram)."
