Hi Alex,
It's so nice and adorable that you have interest in reputable and classic Iranian musicians and music.
Mojir is a prayer that some Muslims in Iran read on certain nights during Ramadan. The prayer has rhymes itself. However, the singer performs it in a more melodic way.
I try to translate it into English through my best knowledge. However, it's not certainly an ideal translation.
Praise be to Allah, O the Most Gracious, You are the Most Superior
O Saviour, Give us refuge away from hell
Praise be to the Most Merciful, O the Most Generous, You are the Most Superior
O Saviour, Give us refuge away from hell
Praise be to the Best King, O the Owner, You are the Most Superior
O Saviour, Give us refuge away from hell
Praise be to the Holy, O the Peaceful, You are the Most Superior
O Saviour, Give us refuge away from hell
Praise be to the Faithful, O the Dominant, You are the Most Superior
O Saviour, Give us refuge away from hell
Praise be to the Most Esteemed, O the Mighty, You are the Most Superior
O Saviour, Give us refuge away from hell

To be continued and this counts around 100 names of God.
There is another famous prayer that is read in Ramadan, called “Joshan Kabir”. It is as rhythmic as Mojir prayer. You can find it with English subtitle through the link below:
