All of the earth is a mosque (prayer place) except the graveyard and the bathroom

Explanation

All of the earth is a place (suitable) for prayer, except for the place where the dead are buried, and this includes all the area inside the fence of a cemetery; and the place where one bathes with hot water for treatment.

An-Nawawi (may Allah have mercy upon him) said: "Prayer in the dwelling places of the devil is disliked by unanimous agreement, such as bars, nightclubs, places where excise taxes are levied, and similar places where sins are openly committed, as well as churches, synagogues, restrooms, etc."
