The book alKafi is the Shiah equivalent to Sahih AlBukhari to Ahlussunnah.
In volume 1, page 237 there is this narration:
Ali bin abi Talib (r.a) was told that the Prophet’s donkey, Ufair, committed suicide! So Ali said: That donkey spoke to the Prophet (sallalahu alaihi wa ala alihi wa sallam), he said: You are equal to my father and mother, my father told me, that his father told him, that his grandfather told him, that his father was with Noah (sallalahu alaihi wa ala alihi wa sallam) on the arc, so Noah (sallalahu alaihi wa ala alihi wa sallam) approached him and wiped over his back and said: from the offspring of this donkey there will come a donkey which will be ridden by the best and final prophet. Ufair then said: so Alhamdulillah, that He made me this donkey.
If we would take into consideration that the average age of an donkey is around 25 and an donkey of 40 years old is regarded as an elderly, also, the oldest donkey alive is just merely 60, and add to this a fact, that between the Prophet (sallalahu alahi wasalam) and Isaa (alahi salaam) there were 600 years, between Isaa (alahi salaam) and Musa (alaihi salaam) there were 1700 years, between Musa and …. you’ll get the point, we can clearly say: Shia narrator Ufayr was mudalis, because he ommited a huge number from his donkey forefathers.
