Musa bin Ali bin Rabah al-Lakhmi says that he heard his father (say that) a blind man was reciting these verses in the time of Sayyiduna Umar (may Allah be pleased with him): "O people, I have come across something strange: will the blind man pay the blood money of the sound man? They fell together and he broke him." This was that a blind man and a sound (sighted) man came to a well and fell into it; the blind man fell on top of the sound man, and the sighted man died. So Sayyiduna Umar (may Allah be pleased with him) ruled that the blind man pay the blood money of the sighted man.
