The ruling on going out for jihad without the father's permission

Question:
Honorable Shaykh, if my father has brothers other than me, and they are not in need of my help, and if they need anything, my brothers will do it for me instead, and they have no valid reason for not letting me go to jihad except the fear that I might be killed in the path of Allah, what is the ruling in that?

Answer:
The ruling is that you obey him, even if he has a hundred sons. Even if they are doing what he needs, as long as he has told you not to go, you must obey him and be dutiful to him, if you want the reward. But if you want to arrange your own opinion, that is up to you. However, if you want the reward and the recompense, obey your father, and do not leave him while he is angry, or without his permission. That is, his right takes precedence; this is the right of Allah, Glorified and Exalted is He.
But some people belittle their father, saying, "My father has no opinion, he has no thought, and he knows nothing." They belittle their fathers, may Allah protect us from that, and they do not turn to them, considering their own opinion better than that of their fathers. This is not permissible. This is not permissible. And we will write: the father. As for saying he is nothing, that he has no piety or scrupulousness, this is not permissible for the son; this is undutifulness to parents.
