I don't know Arabic very well.
Our imam in the mosque says "Allahumma Ajirna Minan Naar" and we say "Ameen" to it.
Now due to lockdown, I hear to radio more often and I noticed that the Imam in the radio says "Allahumma Ajirni Minan Naar "
Is there a difference between the two ?
I asked my teacher but she was also confused.She said that the latter is the correct one according to her knowledge.
