I beg your pardon! It is important to note that "Allah" is the same word that Arabic-speaking Christians and Jews use for God. In Arabic, it is the standard word for "God," used not only by Muslims, but also by Bahá'ís, Eastern Catholic Christians, Eastern Orthodox Christians, Mizrahi Jews and Sikhs.
So, if Allah means God, then Indians, whatever their faith believe in Him! So, are Indians infidels? The real infidels are those who don't believe in Allah (God).
And who is an 'Infidel'?
> An unbeliever with respect to a particular religion, especially Christianity or Islam.
> One who has no religious beliefs.
> One who doubts or rejects a particular doctrine, system, or principle.
So then, are Indians who follow different faiths, infidels? There are more Muslims in India than Pakistan, but they are Indians. Are they also 'infidels'?
There is only ONE God, the supreme, the maker of this universe. So whether you're a Muslim, Christian, Hindu or Sikh, you pray to only HIM. There are no different Gods of different religions. There could be different messiahs, but just one God (Allah).
