Fathwa, - Ruling of the Imaam and those praying behind him if he offered an additional Rak‘ah

Question
Upon offering the Maghrib prayer, the Imaam stood up for a fourth
Rak'ah and we notified him (by saying Subhaan Allaah) but he went on.
Then, all of us prayed the fourth Rak'ah with him and we prostrated
twice after the Salaam. Is our prayer valid?
Answer
All perfect praise be to Allaah, The Lord of the Worlds. I testify
that there is none worthy of worship except Allaah, and that Muhammad
isHis slave and Messenger.
If the Imaam stood up to offer an additional Rak'ah, those praying
behind him have to say 'Subhaan Allaah' loudly so as to notify him.
However, if he resumed the additional one, then they must not follow
him as they know that it is additional. Any deliberate addition to the
prayer nullifies it.
We hope that your prayer is valid because you were unaware of this
ruling, as well you are not obliged to make it up.
However, it would be better for you to make it up so as to stay away
from the difference in opinions pertaining to this ruling. As for the
Imaam, if he did not recognize the notification of those praying
behind him, thenhis prayer is valid.
Allaah Knows best. - - ▓███▓ Translator:->
