«لَا صَلَّى الله عَلِيهْ وَلَا سَلِّمْ»

The expression marks someone as a nobody: a person so insignificant that no one bothers to grant them the customary good wishes. It conveys that the person draws no attention, carries no weight, and is simply disregarded by those around them.

Its force comes from taking a pious formula of blessing and peace, best known from the formula honoring the Prophet, and denying both parts with a doubled 'neither... nor.' Withholding even this routine blessing makes the person seem beneath notice. Because it negates a devotional formula, some listeners may find it irreverent or offensive.

Said of a person who counts for nothing in the speaker's eyes, someone ignored, overlooked, or not worth a second thought. It belittles rather than neutrally describes. Suited only to informal talk where open dismissiveness is acceptable; it is not appropriate in respectful or formal exchanges.
