Musnad Abu Ya'la al-Mawsili 110:147

From Hushaym, who said: Abu Bishr narrated to us, from Sa'id ibn Jubayr, from Ibn Abbas, that a man was with the Messenger of Allah (may Allah bless him and grant him peace) while in the state of ihram, and his she-camel threw him, so he died. The Messenger of Allah (may Allah bless him and grant him peace) said: "Wash him with water and lotus leaves (sidr), and shroud him in two garments, for he will be resurrected on the Day of Resurrection in a state of matted hair (mulabbidan)."
