I heard Abu Jafar Imam Muhammad ibn Ali Al-Baqir (as) say: "The mule of the Messenger of Allah (swt) (peace be upon him and his family) was never stopped from going anywhere it wanted." Imam (as) said: "A man from Banu Mudlij came, and the mule had entered his field of reeds. He prepared an arrow and killed it." Then Imam Ali ibn Abi Talib (as) said to him: "By Allah (swt), you will not leave me until you compensate for it." So he compensated for it with six hundred dirhams.
