Is fighting non-Muslims to repel an enemy considered jihad?

Q: It is known that there are non-Islamic armies fighting the ruler of Iraq alongside us. Is our fighting them under a single banner considered jihad? And is anyone of us who is killed considered a martyr?

A: The one who strives in this cause, if Allah rectifies his intention and he strives to repel oppression and benefit the Muslims, then he is a mujahid in the path of Allah, and he is a martyr if he is killed.
And these armies are not under the banner of the disbelievers, but rather each army is under the command of its leader. So the Saudi armies are under their leader Khalid ibn Sultan, and under the supreme commander the Custodian of the Two Holy Mosques, the Egyptian armies are under their Egyptian leader, the Syrian armies are under their Syrian leader, the English armies are under their English leader, and so on. However, there is an agreement among them regarding the organization that is necessary. Allah the Exalted says: [Al-Anfal: 46]. So organization and cooperation among everyone are necessary so that failure does not occur, and so that the enemy does not become greedy.
And the Prophet (peace and blessings be upon him) was approached by a man who asked him, saying, "If a man comes to me wanting my wealth?" He said: He said, "If he fights me?" He said: He said, "If he kills me?" He said: He said, "If I kill him?" He said: It was narrated by Muslim in his Sahih.
So if this is the case for a person who defends his wealth, how much more so for one who defends his religion, his Muslim brothers, and his inviolable rights? And the Messenger (peace and blessings be upon him) says: .
And you, O Muslim mujahid in this war, if Allah rectifies your intention, you fight for the religion of Islam, for the souls, wealth, and lands of the Muslims, and for the general Muslims and their inviolable rights. You stand against them as an atheist enemy who is more disbelieving than the Jews and the Christians, and you strive to remove his oppression and repel his evil. So the matter is great, and jihad is among the most important obligations in this cause. The one who fights with Saddam is threatened with the Fire; because he aided him in oppression and aggression. And it is feared that he may be a disbeliever if he agrees with him in his claim of divinity and his atheism, or if he considers the killing of Muslims permissible. So the point is that he is a partner with him in oppression and aggression. There is detail regarding his disbelief, and he is threatened with the Fire even if he is from the Muslims; for fighting with the oppressors against their Muslim brothers and their oppressed brothers.
As for the Muslim fighter who is against the oppressor, he is in great goodness. If he is killed, he is a martyr. If he is captured or wounded, he is rewarded. And in every case, he has the reward of the mujahideen, whether he is safe or killed, if Allah rectifies his intention.
