> Can you tell me one other religion which has the concept of caste in religious scriptures?

They may not be having caste-based discrimination but they do have other forms of discrimination. That's why you have terms like heathens, heretics and kafirs.

While I agree that Hindus have more of this caste-based discrimination, a simple search shows that it's not exactly uncommon in other religions in India.
