Dar al-harb designates lands where Islam should be imposed by conversion or force

Evidence

Dar al-Islam means the part of the world in which Islam obtains; dar al-harb means the part which is subject to war, i.e. where Islam does not obtain, and where it ought to be made to obtain, by the classic offer of the alternatives of conversion, subjection and battle. — Norman Daniel, Islam and the West, 2105
