Vacating a region when there is an attack is the wisest move. It means to retreat. It means immigrating. If there is a danger at the door, and if there is no immediate solution, one should immigrate. Immigration does not mean that one would not return to his home later on. Our Prophet (saas) immigrated as well, but he returned victoriously. The Companions immigrated and they too returned victoriously. Immigrating is a solution. - Harun Yahya
