Sayyiduna Khabbab (may Allah be pleased with him) narrates: I saw Hamzah, and we found no cloth to shroud him in except one sheet. When we covered his feet with it his head was exposed, and when we covered his head his feet were exposed. So we covered his head and placed idhkhir grass over his feet.
