I have a close childhood friend, a Muslim at that one, who had a habit of visiting Haji Ali and Siddhivinayak temple on the same day before something auspicious. Like exam results, or even before proposing to a girl. It lucked out well for him with that girl.
Now people would argue what business he has in a Hindu temple? But lots of Hindus visit Haji Ali as well.
That is why Indian Muslims can be so different from their Pakistani counterparts - religion does not make the whole fabric of a person. It's often cultural. But, you have to be a secular Indian to understand that thing which unfortunately is a struggle in Hindutva India. Somewhere in the last decade, we lost that nation.
In a similar way I don't see much in common with Pakistani Hindus. They really look and behave different.
EDIT: Let me add this guy wasn't overly religious. He was always clean-shaven (to impress the girls, of course). But he did observe Ramadan fasting and Halal rules. Religion to him was a private matter. And I would say, not the only Muslim person like that. Loads of them were identical.
It was really nice to hang out in a group and noone really cared what religion you followed. Of course, in my immediate friend circle, that is still the case. But not sure about the rest of India nowadays.
