The Prophet (ﷺ) said: The best shroud is a lower garment and one which covers the whole body, and the best sacrifice is a horned ram.
Sunan Abi Dawud Book 21, Hadith 68
← Previous Hadith Mus'ab b. 'Umari was killed on the day of Uhud. He had only a striped cloak. When we covered his head with it, his feet appeared, and when we covered his feet, his head appeared. Thereupon the Messenger of Allah (ﷺ) said: Cover his head with it, and cover his feet with some grass.

Sunan Abi Dawud Book 21, Hadith 67 Next Hadith → I was one of those who washed Umm Kulthum, daughter of the Prophet (ﷺ), when she died. The Messenger of Allah (ﷺ) first gave us lower garment, then shirt, then head-wear, then cloak (which covers the whole body), and then she was shrouded in another garment. She said: The Messenger of Allah (ﷺ) was sitting at the door, and he had shroud with him. He gave us the garments one by one.
