Musnad Ahmad 3751

It was narrated that Ibn Mas'ood (رضي الله عنه) said: The Prophet (ﷺ) disliked ten characteristics: sufrah (a type of perfume); changing grey hair; wearing gold rings; letting the lower garment drag; showing one's adornment before non-mahrams (for women); stamping the heels; coitus interruptus ('azl); 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; and ruqyah except by means of al-mu'awwidhat (soorahs praying for refuge with Allah).
