“Whoever lives in Daru’l-Harb
and no information is known regarding his conditions, he will be accounted as one among the Ahl (people) of the land. In similar respects, those who live in Daru’l-Islam and there is no information regarding their condition, they will also be accounted as among the Ahl of the land.” (Assarkhassi, al-Mabsut, 3/76)

Ibn Qudama reports that Imam Ahmad states: “It is like this because when a person lives in a state (Dar) he is a part (Ahliha) of that state (Dar). This is why the Hukm of a person of the Dar is practiced, until a means of evidence is found proving otherwise.” (Mughni, 2/404, 1638; 3/478)
