It might also be mentioned that Hijrat is not the only way of escape to Muslims who find themselves in a Dar-ul-Harb. There is another injunction of Muslim Cannon Law called Jihad (crusade) by which it becomes "incumbent on a Muslim ruler to extend the rules of Islam until the whole world shall have been brought under its sway. The world, being divided into two camps, Dar-ul-Islam (abode of Islam), Dar-ul-Harb (abode of war), all countries come under one category or the other. Technically, it is the duty of the Muslim ruler, who is capable of doing so, to transform Dar-ul-Harb into Dar-ul-Islam. The fact remains that India, if not exclusively under Muslim rule, is a Dar-ul-Harb and the Musalmans according to the tenets of Islam are justified in proclaiming a Jihad. Not only can they proclaim Jihad but they can call the aid of a foreign Muslim power to make Jihad success, or if the foreign Muslim power intends to proclaim a Jihad, help that power in making its endeavor a success.
