Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: A man died while in the state of ihram, so the Messenger of Allah (peace and blessings be upon him) said: "Wash him and shroud him in his two garments, and do not apply to him anything that was forbidden to him, for he will be raised on the Day of Resurrection reciting the Talbiyah."
