We are tasked with pursuing those who seek to rebel against the authority of the ruler and undermine security, and we have heard some describe them as mujahideen

Question:
We say: Honorable Shaykh, may Allah grant you success, we are a group of security personnel addressing this question to your eminence, as we have been entrusted in this land with uncovering the plans of those who seek to undermine security or rebel against the obedience of the ruler. We have heard fatwas stating that it is not permissible to pursue, track, or fight these people because they are mujahideen, and that they aim to expel the disbelievers who are fighting Muslims in other countries, such as Iraq. What is the correct opinion in this matter? May Allah grant you success.

Answer:
May Allah assist you. You are in jihad in your work, for you are in jihad because you seek thereby to prevent the people of falsehood and to preserve security, lives, honor, and wealth. So you are in jihad. May Allah assist you and record for you the reward of the mujahideen. And [this is] for the ruler of the Muslims. Your work is a very great deed. So let there be no doubt in your minds.
As for those who issue fatwas that this is their jihad, those who issue such fatwas—are they considered? Or are they from the common people and the unknown? They are not scholars. Has any of the recognized scholars issued a fatwa that this is jihad? Never.
This is a lie. This is not jihad. This is disobedience to Allah and His Messenger, and taking the inviolable rights of Muslims to be permissible, and rebellion against the obedience of the ruler of the Muslims. All of these are major sins, may Allah protect us. So this is not from jihad. Yes, this is in the path of Satan, or in the path of Allah.
Because this means harming the Muslims. As for expelling the disbelievers, that is not your concern. Expelling the disbelievers is the responsibility of the ruler, who grants them safety, allows them to enter for interests they need, and expels them when their term ends. The Messenger (peace and blessings be upon him) said, "Expel the Jews from the Arabian Peninsula." This is an address to the rulers. Therefore, only 'Umar ibn al-Khattab (may Allah be pleased with him) expelled them; the people did not expel them. So the one who expels the disbelievers is the ruler, and the one who admits them is the ruler; it is within the ruler's jurisdiction. And they did not come on their own; we brought them for our interests. They did not come as invaders. They came as invited to perform work, either embassies or companies, or the Muslims brought them for interests. And they have taken safety.
And the covenant of entry. The Prophet (peace and blessings be upon him) said, "Whoever kills a person under a treaty will not smell the fragrance of Paradise," narrated by al-Bukhari. And its fragrance can be found from a distance of seventy years. This is a severe warning. So the one who issues a fatwa that this is jihad is not a scholar. Either he is a misguided scholar if he has knowledge, or he is a compound ignoramus who does not know what jihad in the path of Allah is. Yes.
