In this fatwa:
Answering your questions, Sheikh Ahmad Kutty, a senior lecturer and an Islamic Scholar at the Islamic Institute of Toronto, Ontario, Canada, states:
The word Ameen means: O Allah, accept our prayer or supplication. It is not part of Surat Al-Fatihah.
However, it is an act of Sunnah to say ‘Ameen’ after the conclusion of Al-Fatihah as well after offering duaa.
Prophet Muhammad (peace be upon him) once heard a person making an intense supplication; and he said, “He would elicit an answer from Allah, if he seals it off” ‘When asked, how does he seal it off; he replied, ‘by saying Ameen before closing it.” (Abu Dawud)
We also read from another report that Jibreel taught the Prophet to say Ameen after reading Al-Fatihah.
Furthermore, the Prophet said, “If the imam says ghayr al-maghdhoobi alayhim wala al-daalleen, you should say, Ameen. The angels will say Ameen; and the imam also says Ameen.
So, if one’s Ameen coincides with the ‘Amen‘ of the angels, his past sins will be forgiven.” (An-Nasa’i and others)
Based on this, Imam Nawawi concludes that it is recommended for everyone who reads Al-Fatihah to say Ameen-regardless of whether he is an imam or a follower or praying alone.
One should read it aloud in loud prayers; and he should read it silently in silent prayers.
Likewise, it is also recommended to say Ameen while concluding a duaa (supplication).
Allah Almighty knows best.
