I choose to call my God Allah and I pray 5 times a day to him. Does that make me a Hindu ?
All Dharmic religions are method based and not belief based . There are any number of methods and combinations of methods . The realizations obtained through these methods have been explained through various models of the same reality.
Most methods except the 'Bhakthi'(devotional) ones, do not even need the concept of a God. The method of 'Jnana'(intellectual perception)
forbids the assumption of any deity or God . The method of 'Karma' (action) has more to do with maintaining your everyday thoughts&actions in a certain manner and
is not concerned with whether or not a deity /God is worshipped. The 'Kriya ' methods could be carried out independent of any deity , but most require interventions from certain deities.These deities were
'created' as repositories of necessary energies and qualities by the ancient luminaries.
But in any of these methods , including the 'Bhakthi'(devotional) ones , you are not being rewarded by any judgmental deity/God. Nor will you be punished by any judgmental deity/God. It's simply that , the method itself opens up your perception and energies. If the method is not appropriate it could as well diminish your perception and energies.
What you have stated above is that , you assume a singular God and call him Allah and pray to him in a certain ritual performed five times a day . This is definitely not Kriya or Jnana but somewhat of a combination of things which could be called 'Bhakthi' and things which could be called 'Karma' . The methods existent within Hinduism are so extremely broad based that , almost any religious practice could be explained as one or as a combination of those methods. But such an analysis defeats the purpose of your question I believe .
