Here are the verses from the Hindu Bhagavad Gita:

I am seated in everyone's heart, and from Me come remembrance, knowledge and forgetfulness. By all the Vedas am I to be known; indeed I am the compiler of Vedanta, and I am the knower of the Vedas.

"I envy no one, nor am I partial to anyone.I am equal to all. But whoever renders service unto Mein devotion is a friend,
is in Me, and I am also a friend to him."
https://asitis.com/9/29.html

"All of them—
as they surrender unto Me—
I reward accordingly.
Everyone follows
My path in all respects,
O son of Prtha."

The Sikh faith condemns empty rituals and superstitions. The practice of blind rituals, worshiping of idols and inanimate objects, participating in religious fasts, pilgrimage to holy places, offering of food to sadhus (religious leaders). Believing in any other such rituals, superstitions or fads, or other meaningless rituals will not bring one closer to God or make one a better human being.
