Her son wants to go to jihad and she is preventing him; is she sinful for preventing him?

Question:
May Allah reward you, Honorable Shaykh. This is a woman asking: My son insists on me very much that I allow him to go to jihad to support his brothers, and I am not pleased with it, nor do I agree; because I do not know the reality of this jihad, and I fear that it will come back to us with ideas of declaring people disbelievers and blowing things up. So, am I sinful for preventing him from going there?

Answer:
You will be rewarded for preventing him, because he is exposing himself to the danger of not knowing what it is, and also the danger to his creed, the danger of death, and what is the result? O brothers, jihad has conditions and rulings that must be met. If the one in authority orders jihad, then the people advance, or if the door for volunteering is opened, they advance. Jihad is within the authority of the one in authority; he is the one who orders it, he is the one who organizes it, he is the one who sends the mujahideen, and he monitors and follows up on them. But everyone goes and says, "I am going to do jihad," without knowing where he is going. And he may come back to us, as the questioner mentioned, coming back to us transformed, declaring us disbelievers, killing us, and bearing arms against us, and calling this jihad. Yes.
