- Sā‘: a well-known measure. It refers to the Prophetic Sā‘, which weighs 480 Miskals of good wheat, or 3 liters.
- Mudd: a Shar‘i unit of measurement, which is the handful of a moderate person when he fills his hand with and extends it. Mudd is a quarter of a Sā‘, by consensus among the scholars, and it equals 750 milliliters.
