The Muslim, on the other hand, is taught to feel that he is nothing if not a soldier of the militant force of Islam; he must pray in congregation; he must give proof of the sincerity of his faith by undertaking jihad or active exertion for the spread of his religion and the destruction of unbelief among other men. He is a missionary and cannot be indifferent to the welfare of his neighbours’ souls; nay, he must be ever alive to his duty of promoting the salvation of others by all means at his command, physical as much as spiritual. Then, again, Islam boldly avows that it is good for us to be here, that God has given the world to the faithful as an inheritance for their enjoyment.
