Hazrat Abu Musa (may Allah be pleased with him) narrates that a man came to the service of the Messenger of Allah (peace and blessings be upon him) and said, "O Messenger of Allah! What is the situation of fighting in the way of Allah? For among us, some fight out of anger and some out of zeal." So the Messenger of Allah (peace and blessings be upon him) raised his head towards him, and he raised it because the questioner was standing, then the Messenger of Allah (peace and blessings be upon him) said: "Whoever fights so that the word of Allah may be exalted, he is fighting in the way of Allah."
