allah in arabic language is 'god'.is it nirguna brahmam without any attibutes like sankra advocated but hindus following vedic way of worship go by 'saguna' brahmam with attributes which has all qualities which we call lord vishnu as ''parabrahmam'' as supreme soul -paramathma,creater of universe. while ''allah ' by virtue from above theory,it is just a word 'god'. so who is the god in islam similarly jesus christ was born and his wheareabout from 13 years to 28 years is not answered in christian history.where was he? why son of god, who is powerful be sentenced to crucification in cross?.if u say,he sacrificed his life for the sins of people which means peoples sins from fall of adam/eve to the date of christ death.what about the peoples sins currently living in the world.will he come again to earth and sacrifice again his life in cross? that is why hindus worship lord vishnu who showed the creation of living beings - by resting in water in the bed of coils of serpent with lakshmi in his heart,sentout from his naval umbillical card a flower of lotus in the shape of a lady womb to creat first deva- brahma and subseqent creations followed.lord vishnu showed to the world how he created the universe and human race/living beings unlike other so called jealous gods who showed their blood bleeding.
