From him, from Musa ibn Umar, from Ahmad ibn Al-Hasan Al-Mithami, from Ahmad ibn Muhammad ibn Abdullah ibn Al-Zubayr, from his grandfather, who said: I asked Abu Abdullah عليه السلام about a well into which a mouse or another animal falls and dies, and water from it is used to knead dough - can that bread be eaten? Imam عليه السلام said: "If it has been exposed to fire (baked or cooked), then there is no harm in eating it."
