Dought & clear, - - - - Sifat al-Salaah (description of the prayer) - He translates the meanings of the words of the prayer and adhkaar to himself after saying them in Arabic.

Please could you tell me if what I am doing is permissible or not?
Arabic is not my mother tongue, and sometimes when I pray, after I say
something, I repeat it in English in my mind so as to increase my
focus (khushoo') and to focus more in my prayer. Hence for example
after I say "Sami'a Allahu liman hamidah" in Arabic, I repeat it in my
mind in English ("Allah hears those who praise Him"). Is this
permissible or not?.
Praise be to Allaah.
There is nothing wrong with what you are doing to focus on the
meanings of the words and adhkaar of the prayer in English after
saying them in Arabic. This comes under the heading of pondering the
meaning and keeping it in mind. That is so long as you do not utter
it; rather you say it to yourself in your mind, because the one who is
praying is not allowed to say these words in anything but Arabic if he
is able to say them in Arabic. And Allaah knows best.
