I am from Bangladesh. Here almost everyone exclusively use the word Namaz to refer to Salat. Recently my parents have been pressuring me to use the word Salat in place of Namaz. Their argument goes like this. Namaz is supposedly a word that was used by Zoroastrians to refer to their prayers. Similarly Khuda is a word that was used by Zoroastrians to refer to their god. So we should not use these words. I searched the internet but did not find much supporting these claims. My question is even if these claims are true would using these words be wrong?
Like any library, Islam Stack Exchange offers great information, but does not offer personalized advice or legal verdicts, and does not take the place of seeking such advice from your Mufti, Imam, or other trustworthy Counselor.
