Mumbai was once a group of 7 islands with fishermen villages. On one of the islands there was a temple of local Godess Mumba devi fondly called Mumba Aai (mother). Since the islands were not on the way to anywhere any outsider from mainland Maharashtra or else where went to those islands mostly to visit the Mumba devi temple or any business man there for work also made it a point to visit the temple. On returning home he told people that he had been to Mumba-Aai. So the place came to be known as Mumbai.
