4. Abu Ali al-Ash‘ariy has narrated from Muhammad ibn ‘Abd al-Jabbar from ibn Faddal from Burayd ibn Muhammad al-Ghadiriy from ‘Ubayd ibn Zurarah who has said the following:

“Abu ‘Abd Allah , saw me with a black shoe and said, ‘O ‘Ubayd, what have you to do with a black shoe? Did you not know that it has three negative qualities? It slackens the penis, weakens the eyesight and it is more expensive than other shoes. If a man, who does not have anything except his wife and children, wears it and Allah raises him an oppressor.’”
