It was narrated that 'Abdullah bin Mas'ood (رضي الله عنه) said:

The Messenger of Allah (ﷺ) disliked ten characteristics: wearing gold rings; letting the lower garment drag; sufrah - i.e., khalooq (a type of perfume); changing grey hair - Jareer said: what he meant was plucking it; coitus interruptus (‘azl); ruqyah except by means of almu'awwidhat (soorahs praying for refuge with Allah); intercourse with a woman who is breastfeeding a child (because if pregnancy results, it may interrupt the supply of milk) - but he did not say that it is haram; wearing amulets; showing one's adornment before non-mahrams (for women); and throwing dice.
