Who issues rulings on general and critical issues

Question:
Is it permissible for students of knowledge in the occupied land to replace the people with their intentions and the means of jihad according to the extremists among the scholars in their land, and to engage with others regarding the state of their land or to clarify that?

Answer:
It is not permissible for anyone but the scholars to issue fatwas, nor is it permissible for anyone to issue rulings on matters, especially new, general, and critical issues; only the scholars may issue rulings on them. Furthermore, it is not permissible for a single scholar to issue such rulings; in this time, there must be an authority, a fatwa authority, a scholarly body where scholars gather and discuss the matter, as Allah the Exalted said: It is necessary that this be presented to a group, a group of scholars who are beneficial, controlled by their knowledge and their mindfulness of Allah, a group like 'Umar (may Allah be pleased with him). When a matter came to him, he would gather the Muhajireen and the Ansar, and he was 'Umar, yet he would gather the Muhajireen and the Ansar to consult them on this matter and on critical affairs.
As for the specific issues, if a person has knowledge and a questioner asks him a question specific to himself, then he should issue a ruling based on the knowledge he has. As for the general matters, no one should issue rulings in them except the scholars of knowledge and opinion, and the people of trust who engage with the issue and discuss it. Perhaps some of them have what others do not have. They cooperate in solving its problems and difficulties.
