Chapter: How to shroud a Muhrim
Narrated Ibn `Abbas:
A man was killed by his camel while we were with the Prophet (ﷺ) and he was a Muhrim. So the Prophet (ﷺ) said, "Wash him with water and Sidr and shroud him in two pieces of cloth and neither perfume him nor cover his head, for Allah will resurrect him on the Day of Resurrection and he will be saying 'Labbaik' . "
