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) commanded: "Let him be washed with water and lote-tree leaves, let him be shrouded in his two garments, and let his face not be covered, for he will be raised on the Day of Resurrection calling out the Talbiyah."
