«اِلسَّاكِنْ عَدُو مَاكِنْ»

The saying, voiced from the property owner's side, casts the renting occupant as an adversary who has already gained a foothold inside the owner's property. Because the house belongs to someone else, the occupant has little reason to protect it and may even let harm come to it, or cause it, out of resentment toward the landlord.

The word for 'firmly placed' stresses how hard such an opponent is to dislodge. Once installed, the tenant can stall on rent and resist eviction, leaving the owner with a costly, tiring struggle to recover both payment and possession.

Fits property owners' complaints about a tenant who neglects or damages the premises, delays rent, or will not leave without a legal fight, or serves as a wry warning to would-be landlords. It is a sweeping, cynical generalization about tenants, not a neutral observation.
