Musnad Ahmad 2576

It was narrated from Ibn 'Abbas (رضي الله عنه) that A man was thrown from his mount when he was in ihram and died. The Messenger of Allah (ﷺ) instructed them to wash him with water and lotus leaves and shroud him in his two garments, but not to cover his head, for he would be raised on the Day of Resurrection reciting the Talbiyah. And Ayyoob said: With his hair stuck together (with a sticky substance, as was the custom of pilgrims at that time).
