Narrated Abdullah ibn Abbas: The Messenger of Allah ﷺ recited the supplication (Qunut) daily for a month at the noon, afternoon, sunset, night and morning prayers. When he said: "Allah listens to him who praises Him" in the last rak'ah, invoking a curse on some clans of Banu Sulaym, Ri'l, Dhakwan and Usayyah, and those who were standing behind him said: Amen.

➊ In the obligatory prayers performed silently, the Qunoot will also be recited aloud (with a raised voice). And the followers (muqtadis) will say "Ameen."
