It was narrated from Ata bin Saib from his father, from Ali that the Messenger of Allah ﷺ came to Ali and Fatimah, when they were covered with a Khamil belonging to them. And a Khamil is a white velvet made of wool. The Messenger of Allah ﷺ had given this to them as a wedding gift, along with a pillow stuffed with Idhkhir and a water skin. (Sahih)
