Musnad Abu Ya'la al-Mawsili 110:10

Al-Mu'alla narrated to us, Abu 'Awanah narrated to us, from Abu Bishr, from Sa'id ibn Jubayr, from Ibn 'Abbas, that a man was killed by his camel (while in the state of Ihram). The Messenger of Allah (ﷺ) commanded that he be washed with water and lotus leaves (sidr), and that he should not be touched with perfume, nor should he be shrouded, nor should his head be covered. And he said: "Indeed, he will be resurrected on the Day of Resurrection in a state of matted hair (mulabbidan)."
