Is it permissible to recite tasbih when the imam says in the qunut supplication, “You decree, and no one decrees over You”?

Question : He says: In the qunut supplication, when the imam says, “You decree, and no one decrees over You; You do not humiliate the one You have favored, for the one You have humiliated has no favor,” the ma'mumin (those praying behind the imam) recite tasbih and say, “Subhan Allah” (Glory be to Allah). Is this tasbih prescribed in this place?

Answer : Yes, tasbih and hamd (praise) are prescribed, because the fact that He decrees makes Him worthy of praise, and the fact that no one decrees over Him makes Him worthy of tasbih, similar to saying, “Subhanaka wa bihamdika” (Glory be to You and praise be to You).
