What is the ruling on qunut in times of calamity without the imam's permission?

Question:
What is the ruling on qunut in times of calamity without the imam's permission? And what is the ruling on saying "Ameen" behind one who performs qunut if it is not permissible?

Answer:
Qunut in times of calamity is among the prerogatives of the one in authority. This is done based on a fatwa from the scholars of knowledge. If the scholars to whom issuing fatwas is entrusted—the ones who issue fatwas in general matters—issue a fatwa to this effect, the one in authority generalizes it among the people, and they act upon it. As for the one who performs qunut without a fatwa, he is mistaken. However, the prayer is valid; it is permissible to pray behind him, and the prayer is valid, if Allah wills, even though he is mistaken. But the strange thing is that they perform qunut without a fatwa, and when a fatwa is issued regarding qunut, they refrain from performing it. This indicates that they want to oppose and contradict. Yes.
