«قُولِةْ لَوْ كَانْ تُوَدِّي الْمُرُسْتَانْ»

The proverb warns that clinging to counterfactual 'law kān' thinking, meaning 'if only it had been' rather than a plain 'if', is pointless and harmful. Repeating 'if only things had gone differently' changes nothing that has already happened. It only wears down the person who cannot let go of it.

The destination is the murustān, a popular reshaping of a Persian-derived word for hospital, narrowed to mean an asylum for the insane. The exaggeration pictures obsessive regret as a road to losing one's mind and nudges the listener to accept what is done. The image reflects older attitudes toward mental illness and may sound stigmatizing today.

Said to someone who keeps replaying a missed chance or a regretted decision, urging them to stop. It fits consoling or mildly scolding moments in everyday talk, often after a loss that can no longer be undone.
