The Quran in Salah must be said in arabic, I don't expect there to be any problem in that. Other than the Qur'an, there are only few phrases in arabic that need to be learnt and said. And then one may add whatever dua in ones own language for example in sujuud etc. Thus many of us end up praying in our own language as well.Originally Posted by NoNameAtAll
I have heard of a position with some ulama, that state that one may say everything else in salah, except the Quranic passages, in whatever language. Allahu alim, though. It may have something to do with the fact that saying subhaana rabbiyal aala for example is not classed as a fardh in a certain madhab, so then according to the same madhab one may even leave it out (and then replace with something in one's own language). I will try (or you can try as well) to see how sound such a position is within any madhab, or in sunni islam altogether.
But my humble advice would be to just follow the sunnah of the Beloved Prophet as it is, without altering a single thing. Surely, if we (as we should) do it out of love for the Blessed prophet we will only gain, no?
As to the hadith in question, it is best laymen are not the ones to deduce rulings with our logic, as the scholars surely have much more understanding of what kind of logic can be used and what not.
