This is a pretty good definition of the first, Dar al Harb / Dar al Harab. While it says the term has little relevance today because of the fragmentation of the Ottoman empire, that’s not true, because the terrorists- ISIS in particular- do indeed think of themselves as the Islamic state/empire reborn.
This is a good definition though, because most other sources attempt to redefine it to mean simply any non-islamic state at war with Islam [leaving the reader to assume it means the nonislamic stste initiated hostility.] But that’s not at all what it means, and it is a deliberate effort to eliminate the fact that it actually means any nonislamic state that is in a state of resistance to an Islamic demand for it to convert to Islam - in other words, the aggressor is actually the Islamic state and it is the Islamic state making the demand to convert. They of course ddon’t see that as aggression on their part, they see it as defiance of Allah.
These dar al Harb / dar al whatever terms do not appear in the Quran but arose later in Iraq during islamic ascendency and the ideas spread from there. The problem with islam is that much of it in practice doesn’t even come from their “holy book,” but from hadiths and later tradition, largely political rather than theological tradition developed when it was one empire..
