If the imam recites qunut in the Fajr prayer and the ma'mum does not see the qunut, does he say "Ameen" to his supplication?

Question : Even Imam Ahmad (may Allah have mercy on him) said: If a man prays behind an imam who recites qunut in the Fajr prayer, does he say "Ameen" to his supplication or not?

Answer : He says "Ameen" to his supplication. He does not say, "I see that I am committing an innovation and I am not following the imam." No, he says: Follow your imam and say "Ameen" to his supplication, even if you do not think it is correct.
