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