(17) باب الْخِضَابِ بِالصُّفْرَةِ
It was narrated from 'Abdullah bin Mas'ud that:
The Prophet of Allah [SAW] 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)- but he did not say that this is Haram.
