Musannaf Ibn Abi Shayba 35:204

Hushaym narrated to us, from Abu Bishr, from Sa'id ibn Jubayr, from Ibn Abbas, that a man was with the Prophet (peace and blessings of Allah be upon him) while he was in the state of ihram, and his she-camel threw him, so he died. The Messenger of Allah (peace and blessings of Allah be upon him) said: "Wash him with water and lotus leaves (sidr), and shroud him in his two garments, and do not cover his head, for Allah will resurrect him on the Day of Resurrection reciting the talbiyah."
