Safiyya bint Shayba bin 'Uthman · The Book of Adornment

The Prophet of Allah disliked ten things: Yellow dye, meaning Khaluq, changing gray hair, dragging one's Izar, wearing gold rings, playing with dice (Ki'ab), (a woman) showing her adornment to people to whom it is not permissible for her to show it, reciting Ruqyah, unless it is with Al-Mu'awidhat (Verses seeking refuge with Allah), hanging amulets, removing to ejaculate in other than the right place, and taking away the milk of an infant boy (by having intercourse with his mother)-…

"The Messenger of Allah said: 'The Izar should come to the middle of the shins and the calf. If you insist, then a little lower, and if you insist, then a little further down, but the Izar has no right to (come to) the ankle." This is the wordings of Muhammad.
