This Malay Jawi writing. It was widely used in Brunei, Malaysia, and Indonesia (in other word, Malay-speaking world).

No particular country shall take credit on the usage of Jawi writing here. It is a mutual heritage of Malay language.

This translation is done in Jawi writing for:
1) The song would be the same in Malay. Indonesian is a registered variety of Malay language (refer Wikipedia).
2) To keep the heritage of Malay language by using the traditional writing whenever it is reasonable.

Thank you!
