‘Ubada b. as-Samit reported God's messenger as saying, “The best shroud is a lower garment and one which covers the whole body, (The Arabic has al-kulla, which means the two garments known as the izar (lower garment) and rida' (a cloak which covers the whole body)) and the best sacrifice is a horned ram."
Abu Dawud transmitted it; and Tirmidhi and Ibn Majah transmitted it from Abu Umama.
