«بِفْلُوسَكْ حَنِّي دُرُوسَكْ»

The saying defends a person's freedom to make even foolish-looking choices with resources that belong to them. Its deliberately absurd image—dyeing molars with henna—underscores that others may dislike a purchase without gaining authority over it.

Its point changes when the spending draws on someone else's property or imposes costs on others. The proverb is not a blanket approval of every action: it distinguishes private extravagance from conduct that invites legitimate objection because another person bears the expense.

Used when someone criticizes another person's harmless but seemingly wasteful personal spending. It can dismiss unsolicited interference, while also implying that the defense applies only when the person truly bears the cost themselves.
