«فِي الْوِشِّ مْرَايَهْ وِفِي الْقَفَا سِلَّايَهْ»

The saying exposes the hypocrite who, when facing you, becomes your flattering echo, nodding along and mirroring your views. The mirror here means agreeable imitation and warmth, not honesty or showing you your true self.

Once you turn away, that same person stabs you behind your back like a sharp thorn, slandering or undermining you in your absence. The smooth mirror and hidden barb show how friendly appearances can mask quiet hostility.

Use it to describe or warn about a two-faced person who agrees with and charms someone face to face but speaks ill of or harms them behind their back. It is pointed criticism, suited to private remarks or cautionary advice about false friends.
