Hazrat Musa bin Ali (may Allah be pleased with him) narrates that his father, Hazrat Ali (may Allah be pleased with him), said: During the time of Hazrat Umar, a blind man was reciting this verse to the people: Translation: O people! I am faced with an unreasonable matter. Should a blind man also pay blood money to the one who can see? Even though both of them fell together and both of their bones were broken? Hazrat Waki’ says that people held the opinion that a sighted man was taking a blind man along, and both of them fell into a well, and the blind man fell upon him—either he killed him or injured him—so the blind man was held liable.
