It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that a man was brought to the Prophet (peace and blessings be upon him) whose mount had thrown him; he died while he was in the state of ihram. He (peace and blessings be upon him) said: "Shroud him in two garments, wash him with water and lote-tree leaves (sidr), and do not cover his head. Indeed, on the Day of Resurrection Allah Almighty will raise him, and he will come reciting the talbiyah."
