Theory 1 (based on Brunei History, that was written by the Sultan writer)
It was began from the assasination of Sultan Muhammad Ali's son. It was happened because of cook fight. Cook belonging to the Sultan Muhammad Ali's son was lost and that makes him angry then killed the Bendahara son which is Pangeran Bendahara Abdul Mubin's eldest son. The Bendahara so angry with that incident and marching to the palace to seek the revenged. But the Sultan denied it and asked him to checked the palace if his son was available. When his men never saw the Sultan's son, he started to killing everybody in the palace including the Sultan.
Brunei had no Sultan after Sultan Muhammad Ali was killed by the Bendahara. To governed the country, Bendahara was appointed to be the next Sultan because he had the close blood relationship to the previous sultan (Sultan Muhammad Ali was his uncle). Sultan Abdul Hakkul Mubin was appointed Pangeran Muhyiddin as known as Pangeran Bongsu to be his Bendahara to make foster peace between his followers and previous sultan's followers. But Pangeran Bongsu betrayed him. He makes chaos in the country and it pushed the sultan to move at Pulau Chermin. When the sultan stayed there, Pangeran Bongsu took the throned and it was makes the sultan felt betrayed. Then the civil war happened.
Pangeran Muda Bongsu called his name as Sultan Muhyiddin and he makes strike to Sultan Abdul Mubin fort at Pulau Chermin but he was failed. He asked help from Betara Sulu to attacked Sultan Abdul Mubin and as a reward, he will give HALF of north Borneo which is the land called Saba' to the Betara. After several years of war, the Betara defeated Sultan Abdul Mubin who was retreated to Kinarut, Saba'. That is why the Sultanate of Sulu always claiming Sabah as their belonging until nowadays. They claimed that Sultan Abdul Mubin was died in Pulau Chermin but there are no grave in the island that found until today.
Theory 1 conclusions:
1. Sultan Abdul Mubin was known as a 'throne prowler' in old Brunei history. But his intention just to seek the revenged after his son was killid by Pangeran Muda Alam. Not more than that. He was appointed as a Sultan by the peoples who want him to be the sultan replacing Sultan Muhammad Ali.
2. He was insulted by the historian of Brunei. What is the reason why he was insulted by the historian? It is because of his killed the previous sultan? How about his son who was stabbed by Pangeran Muda Alam? Anyone can feel his sadness? Think it.
3. His right was denied as a Sultan by his own Bendahara who was betrayed him. The Bendahara should not offering any gifts or royal colony to the peoples because he does not have any rights to do it except the sultan give the order or permission. In this context, Muhyiddin was not the Sultan. He is the one should be insulted by the historian because he took the throne from the Sultan and that time Sultan Abdul Mubin was still the legal sultan.
4. Muhyiddin gave the land called Saba' to Betara Sulu as a reward to help him against Sultan Abdul Mubin. But it was no legal because there was no any black and white letter or agreement on it. He just gave it by his words not his letter and royal seal. The royal seal was in hand of Sultan Abdul Mubin.
5. Effected from that, Muhyiddin asked the palace writer to remove Sultan Abdul Mubin history from Brunei Sultanate history until Mr. Yusin Hj. Boaklan and his fellows called the Brunei History Centre in 2004 to published the history of the sultan. Sultan Abdul Mubin history was lost almost 500 years! Can u imagine that?

Theory 2 (based on several books <actually it was bought and hidden by the current government of Brunei> and old folks story that their inherit by their ancerstors in Sabah.
It was began by unsatisfied of Pangeran Bendahara Abdul Mubin to the sultan because of his majesty bad treatment to the peoples of Saba'. Generally, the sultan already gave and divided the 'kawasan pegangan' or area of administration to his high officers and as Bendahara, he was appointed to keep the land of Saba'. The peoples in Saba' was very poor and always facing the natural disasters. So he always adviced the sultan to help them if he want the support of the peoples from Saba'. But the sultan was refused and this makes him dissapointed. According the books written by Mr. Yusin Hj. Boaklan, Sultan Muhammad Ali was a weak ruler. He always wasting his time at the palace with the maids and concubines. He never take care of his kingdom and this is make Pangeran Bendahara was angry and dissapointed with him.
Sultan Abdul Mubin fort in Kinarut. His Majesty was stayed there almost 10 years.
When the Bendahara always pushed the sultan and keep asked him to help the peoples, he felt uneasy and try to against the Bendahara. Actually the Bendahara was afraid if the peoples of Saba' will rebel to the kingdom but the sultan misunderstand it. As the climax of this relationship between Sultan and Bendahara, Pangeran Bendahara Abdul Mubin went to Saba' because of the natives invitation. They discussed with him and asked if possible if they want to withdraw from the kingdom of Brunei because they was too suffered.
Lately, the peoples of Saba' was rebelled and wanted the Bendahara and his family be the sultan in Saba'. The Bendahara men killed the sultan and appointed Pangeran Bendahara as a new sultan of Brunei. But he was opposite by previous sultan's son in law. Then Sultan Abdul Mubin retreated to Kinarut and built a palace there. The peoples of Bajau and Dusun was the loyal followers to him.
Theory 2 conclusions :
1. Why Pangeran Bendahara Abdul Mubin was accepted by the peoples of Saba'? It was because he was well known since his father became previous Bendahara the one who kept Saba' as Sultan's representor.
2. His relationship with the peoples more better than the sultan. Because he always went to Saba' to heard the peoples problem. Why he did not went to Sarawak even its also in area of Brunei Kingdom? It was because, Sarawak is under Digadong power, so Bendahara should not interfere on that area.
3. Pangeran Bendahara Abdul Mubin decendants was from Saba'. That was why he accepted by the peoples of Saba'. His ethnic is Sama Balingingi from the noble clan and supreme Datu of Saba'. Why he is related with Brunei? It was because he also has a bloodlink with the Sultan Hassan from his mother side.
4. The native accepted him as a Sultan of Saba'. This is stated in old Brunei manuscript and this was certified by Muhyiddin when he asked help from Betara Sulu.
This research is under going. What makes me dissapointed is the Brunei History Centre does not want to give fully cooperation in this research. Seems they hide something when we asked about Abdul Mubin history.
It was a big research because we discovering that the history must be reveal and peoples has to know. We just afraid our children lost their identities and they would not knows the real story of their ancestors. I am just discovered the linkage and relationships between the Malay in Borneo with Malay in Indonesia and Phillipines through this research.
I hope my fellows and I could discover it sooner. God's will.
