It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that a man in the state of ihram was with the Prophet (peace and blessings be upon him); his she-camel threw him and he died. The Messenger of Allah (peace and blessings be upon him) said: "Wash him with water and lote-tree leaves (sidr), shroud him in two garments, do not apply perfume to him, and do not cover his head, for he will surely be raised on the Day of Resurrection with his hair matted (mulabbid)."
