When praying with the Imam is it necessary to say Ameen before him or after The saying of him?

In Islamic prayer, it is not necessary to say "Ameen" before or after the Imam. The Imam leads the prayer and recites the necessary supplications aloud, and the followers generally listen and follow along silently. However, some scholars suggest that it is permissible for the followers to say "Ameen" softly after the Imam completes a supplication. This practice is not obligatory but considered a recommended act.
