In Manhaj as-Salikin lesson 4, you said men can only wear silver rings because the Prophet used to wear it. But did he explicitly forbid other accessories? If not, isn't the asl is that everything is permissible unless the Prophet forbade it? I'm confused. Please give reference for it.

The eminent scholar Ṣāliḥ al-Fawzān (may Allah preserve him) said: "This is unlawful; this is imitation of women. Wearing bracelets is among the distinctive features of women, so men are not to wear them. The Prophet (ṣallā Allāhu ʿalayhi wa sallam) cursed men who imitate women, and he cursed women who imitate men."
