If you find a Muslim fighting with an Islamic group; do you fight him or do you pray for his guidance?

The questioner : ... regarding fighting with an Islamic group, is it permissible for me to fight him and to pray for his guidance?

The Shaykh : When does this fighting become necessary? I told you: this fighting has a time when you must advance. What do you mean by fighting?

The questioner : When the Muslims left the Arabian Peninsula and came to the land of Sham, they presented three matters to the Romans and then fought them. So it is natural that it is permissible for the Muslims to pray for the guidance of the Romans; so how do we accept that at the same time it is permissible for us to pray for their guidance and fight them? Why don't we leave them until Allah (Glorified and Exalted is He) guides them?

The Shaykh : No, there is no contradiction if you know or remember the goal of the fighting. The goal of jihad is to bring them into Islam, but people do not all come willingly in the best manner, ; the goal of the fighting is the testimony, meaning faith in Allah in His oneness and in the Messenger in his message, and the goal of the call; is it not this as well?

The questioner : But they abandoned this path.

The Shaykh : Is it not this? Yes, I know the method you are correcting me on. Do not correct me. I know that this path aims at guidance, and this path aims at guidance; so there is no contradiction between the two paths. But sometimes a Muslim finds himself satisfied with the first path, which is what? The call. And sometimes he finds that this is not sufficient and has not achieved the greater objective; so jihad in the cause of Allah is necessary to achieve what you intended with the call itself. But the call, as I told you at the beginning, may not achieve the desired purpose in some cases and in many cases, so the Wise Lawgiver legislated another means of using force to achieve the purpose of the first means.
An example that clarifies what I am going around: His saying (peace and blessings be upon him):
-- And upon you be peace and the mercy of Allah and His blessings --
So we find the Messenger (peace and blessings be upon him) in this hadith established two paths for reward: If you cannot reward him, pray for him until you know that you have rewarded him. So material reward is not something everyone can do; therefore the Messenger (peace and blessings be upon him) established another path for the one unable to give a material reward... You, O Allah, reward him with good, O Allah, guide him, O Allah, enrich him with Your lawful and keep him away from Your forbidden, and so on. And because of the ease of this means and this path, people have relied on it, especially scholars like us. When someone presents them with a material gift worth so much, what will be the reward? A righteous prayer. And that poor person is satisfied with this prayer; because he seems to imagine that the one praying for him is a prophet, and his prayer is answered by Allah. If that were the case, he would be satisfied with it, of course. He presented to him, for example, a gift worth ten, twenty, a hundred, two hundred; he prayed for him a prayer containing good in this world and the Hereafter, and he would be satisfied with it. But this person is not a prophet.
And if it happens that Ibn 'Umar, pardon, 'Umar himself, it is narrated from him that one day a man came to him and said to him: Pray for me, O 'Umar. He said to him: Are we prophets? Yes, this is 'Umar al-Faruq, the one from whom Satan fears. But among the wonders of paradoxes is that he fears Satan, , this is the testimony of the Messenger (peace and blessings be upon him) for him; nevertheless, he fears Satan more than we fear this Satan; as evidenced by the fact that when he saw people coming to him, seeking blessing from him, and asking for his prayer, he came out to them; he said to them: Are we prophets? You always ask us for prayer, as if we are what? Meaning, arrogance and self-admiration do not enter us. We are not prophets and we are not infallible; so he fears Satan!!
The point of the speech, we expanded a little, so the Messenger (peace and blessings be upon him), just as he established two paths for reward, material and prayer, so the path of guiding people has two ways. A way within the reach of the weakest of people, like saying: May Allah reward you with good, to the one who gave you money. And a way that is not made easy for all people, but for some of them, and this some, as well, is not made easy for them to do jihad, as we are placed in this time; so the fact that the call is legislated for the one who stubbornly persists, as jihad is legislated for him, there is no contradiction between the two matters; because they meet in the path of achieving one purpose.
