There is no doubt that if this question comes first who is following the ancestors, going to Hindu temples, and watching   Ramayana  , then the answer is the Indonesian Muslims. The Indonesian Muslims surprisingly would already know that their ancestors were Hindu and they have also realized that they have been converted hence they do not want to forget the traditions of their ancestors.

This shows how   Indonesian Muslims   were so educated about Hinduism and know about watching Ramayana as they know the reality.

In comparison if we talk about Muslims here, they change their mind very quickly as if someone influences them, hence they seem to be brainwashed because they are not educated, do not want to develop their thinking and they talk negatively because they do not understand the reality.

These Indian Muslims are always influenced by people who think about terrorism, extremism, and actions against humanity. 

Indian Muslims always go to madarsas schools to get their education and you won't believe the vast majority of graduates from   Madrasas   in Mewat find themselves employed in low-skilled positions within shrines, mosques, or other Madrasas. A smaller fraction opts for careers in farming. Only 3% of individuals achieve an elevated level of socioeconomic development.

Most Muslim families residing in Mewat express their desire for Madrasas to offer technical education and vocational training. The study's findings reveal that religious authorities, despite having the power to approve modifications, oppose contemporary education.

And Muslims who persisted in their preference for Madrasas as opposed to other educational establishments realized that they were deficient in the necessary competencies for lucrative job opportunities as societies progressed.

There is no doubt in education that their madarsa system is working and the head of madarsa is giving wrong education to Muslim people. Due to this, the coming generation will start following the practices. With that being said, these people could not understand about Ramayana.

Top facts about Indonesian Muslims who watched ramayana

That's the surprising thing how Indonesian muslims being the muslim country follows   hinduism   and watch ramayana because they know their ancestors and well educated about the traditions given by them. 

Thе fascination of Indonеsian Muslims with thе Ramayana is dееply rootеd in thе nation's cultural amalgamation. While Hinduism arrived in Indonеsia cеnturiеs ago, it coеxists pеacеfully with Islam. Thе Ramayana has bеcomе a sharеd cultural hеritagе, cеlеbratеd through traditional dancе-dramas, known as "Wayang Kulit" and "Wayang Wong," which narratе thе еpic's talеs.

Indonеsian Muslims attеnding Ramayana pеrformancеs viеw thе еpic not mеrеly as a rеligious narrativе but as a cultural mastеrpiеcе that transcеnds rеligious boundariеs. Thе artistic еxprеssions, vibrant costumеs, and rhythmic pеrformancеs crеatе a captivating spеctaclе, fostеring a sеnsе of unity among Indonеsians rеgardlеss of thеir rеligious affiliations.

Thе Indonеsian approach to thе Ramayana rеflеcts a broad commitmеnt to intеrfaith harmony. Thе nation's Pancasila idеology, which еmphasizеs rеligious divеrsity and unity, еncouragеs mutual rеspеct among diffеrеnt rеligious communitiеs. This inclusivе еthos has pavеd thе way for thе intеgration of Hindu cultural еlеmеnts, such as thе Ramayana, into thе broadеr Indonеsian cultural miliеu.

In my opinion, Indonesian people are way too good and they are following the rituals of Hinduism in a good way

Our Hindu religion has developed so much during that time that we can see it through    Akhand Bharat  . Hindu kings have achieved so much success in spreading this religion which even Indonesian Muslims know because they are educated.

Comes to the end, Indonesian Muslims are following the right path of Sanatana dharma, are aware of the Ramayana and its scientific significance, and always follow Hindu rituals which we cannot see in Indian Muslims. Not only Indonesian Muslims, but all over the world several countries like the USA, Australia, and so forth are following our Hindu Sanatana Dharma. 

In a nutshell, Indian Muslims should learn the teachings of Sanatana Dharma and know the reality check behind the significance of Lord Ram that I think will be possible after the establishment of Ram Rajya.
