When is jihad an individual obligation?

Question:
He says: Everyone knows what Muslims are facing in many places in Palestine, Iraq, and elsewhere. The question is: When does jihad become an individual obligation, and what is its ruling in this time? He says: I need your answer because I am in complete need of it.

Answer:
Jihad becomes an individual obligation for the people of a country that has been attacked, provided they have the ability to defend it. It is an individual obligation for everyone among the people of the attacked country who is capable. As for others, they assist them with money and with supplication, provided there are conditions for the assistance that involve no harm and ensure it reaches the Muslims without any danger. Conditions are necessary. If it is organized and has a system under the state and the authorities, through known channels, then one follows that, so that it reaches them without any harm coming to the Muslims.
As for jihad with them, this requires two things. First, obedience to the ruler in this matter. If the ruler sees fit and prepares an army to help the Muslims in a certain country, then jihad in this way is among the greatest acts of obedience.
The second thing is that obedience to the parents is necessary. Obedience to the parents is necessary in voluntary, recommended jihad. So, first, it must be with the ruler’s permission and under his organization, and second, obedience to the parents, so that the parents are not in need of him. How can he leave them? So, he must take their consent. If the ruler gives you permission, you must also seek permission from your parents. Yes.
