Question: The wearing of [friendship] string bracelets amongst the male students in schools has [now] become widespread, so what is your opinion regarding that?
Response: This is prohibited, [because] this is resembling the women, [as] the wearing of bracelets is something specific to women. So males should not wear them, as [the Prophet] ﷺ cursed those from amongst the men who resemble the women, as well as those from amongst the women who resemble the men.
