Why do we raise our hands when we say “allahu akbar”?
Answer: We know well that any language if you translate it into another lanuguage we can not express the same maening and context what has said in original language. for eg in the zikr Ruku we say "Subhana Rabbi al Adhim e wa behamdehi" and in Zikr of Sajda we say "Subhana Rabbi al A'ala wa behamdehi" now what is the difference between "Adhim" and "A'ala" as in english we say Great and High but it is not exactly what it is meant in Arabic. also Itself Sura Hamd what context it has in Arabic no one can translate it into other language as it has said in Arabic. Therefore it is wajib to recite Namaz in Arabic.
Also Islam wants to maintain Unity amongst all Muslims and if every person comes and start reciting Namaz in his own language they will most surely do something less or more but if they recite it in Arabic they will maintain what Holy Prophet (sawt) has said and recited it exactly.
