Musannaf Ibn Abi Shaybah

Hazrat Ibn Abbas (may Allah be pleased with them both) narrates from the Noble Prophet (peace and blessings be upon him) that a man fell from his camel and died, so the Prophet (peace and blessings be upon him) said: "Wash him with water and lote tree leaves, and shroud him in his (same) two garments, and do not cover his head. For Allah, the Exalted, will raise him on the Day of Resurrection reciting the talbiyah." And (Imam) Abu Hanifa's opinion has been mentioned that: his head should be covered.
