The prophet, peace be upon him, prayed in his native language which he can easily understand. Also there is a hadith that states you should take a breath between surahs while saying prayer and I think it is so that you can understand what you are saying. What other reason could it be? Praying in Arabic does not accomplish these things.
Is there really nothing that specifically talks about praying in Arabic, so that I feel that it is the right thing to do?
I am a "man of understanding" and do not accept someone else's interpretation when the reasoning is not clear or sensible. It is not sensible to pray in a language that you cannot understand. period.
Interestingly, the Bible has no quote of the prophet Jesus saying "Worship me". Seems the same lesson/trial/test to me. Though Id rather mess up prayers than break the first commandment :)
For sure I am not praying in Arabic if there is nothing specifically saying this in the Quran or Hadith. Thank you for the answer(s). Praise God that he has made Islam a clear religion, and truly it is a mercy upon us full of blessings and peace of mind.
