Question Summary:
Saying aameen in Salaah

Question Detail:

When we pray salah individually do we say ameen after reciting surah fatiha? or is that only when praying in congregation behind an imam?

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
 
When a person performs salah by himself, he should say the aameen after surah fatihah.[1]
 
And Allah Ta’āla Knows Best
