Nation State Or States Based On Conquests
It is not true that Islam does not have any objection to capture a state. Any act of oppression against anybody, whether it be against an individual or a state is prohibited. The only condition in which Jihad is permissible to Muslims is to counter oppression (‘ zulm ‘) only. During the era of Khulfa-e-Rashideen, there were battles fought under the law of itmam-e-hujjat. What Muslims did after their era is solely their responsibilty and it does in no way affect the Islamic principle of و امرهم شوری بینهم.
