Reign

Establishment and accession The have written stories about him, although some have added to and varied from the originals. In the genealogy version of Datu Imam Ya'akub and Khatif Haji Abdul Latif, Pengiran Raja Tengah Ibrahim Ali Omar Shah is the son of Sultan Muhammad Hasan and was crowned king of Sambas in addition to being the Sultan of Sarawak, is extensively described in the genealogy version of Pehin Orang Kaya Digadong. He was commonly recognised as the son or grandchild of Sultan Abdul Jalilul Akbar. However, Sambas's sources gave the precise birth date of his son, Raden Sulaiman, as 14 April 1601. Sultan Abdul Jalilul Akbar may have anticipated the rivalry between him and his brother, which may have contributed to the creation of the Sultanate of Sarawak. Consequently, he named his younger brother Sultan of Sarawak, taking into account the fact that Sarawak is a remote region of Brunei. Pengiran Raja Tengah Ibrahim Ali Omar Shah, was proclaimed the first Sultan of Sarawak by his brother, Sultan Abdul Jalilul Akbar, in 1599.

Heading off for Sarawak, Sultan Ibrahim Ali Omar Shah took a total of one thousand men (Brunei people who reside in Kampong Saba) with him.

Sultan Ibrahim Ali Omar Shah made the decision to leave the Sukadana Sultanate and relocate to the Sambas River region after around 7 years of settlement there, as the conditions near the Melaka Strait remained dangerous. With forty boats fully armed, the Sultan departed Sukadana in 1638 and made his way to Panembahan Sambas on the Sambas River. King of Panembahan Sambas at the time, Ratu Sapudak, gave the Sultan's delegation a warm reception. Ratu Sapudak then gave his approval for the Sultan to relocate to an area close to the Panembahan Sambas administrative headquarters. Soon after, Ratu Sapudak died, and Raden Kencono took the throne, assuming the name Ratu Anom Kesumayuda. as a consequence of a disagreement with Pengiran Mangkurat, the first Vizier of Sambas. The genealogy also describes how Raden Bima, the prince of Raden Sulaiman, faced Sultan Muhyiddin in Gelagak (Kalakah) and was then taken to Brunei where he was crowned Sultan of Sambas, succeeding his father as Sultan Anom.

Sultan Ibrahim Ali Omar Shah made the decision to go back to Sarawak soon after he noticed that the area around the Melaka Strait had become safer and that his son Raden Sulaiman had married and taken on the role of Minister of Panembahan Sambas. The Sultan returned to Sarawak in 1652, accompanied by his wife Puteri Surya Kesuma and her four children (Badaruddin, Abdul Wahab, Rasmi Puteri, and Ratna Dewi). Following his death, the Sultan's remains were interred atop Bukit Santubong's slopes in accordance with the customs and tradition of the Sarawak Sultanate. Sarawak was ruled by the four native datu until the first White Rajahs came in 1842, according to tradition, following the death of Ibrahim Ali Omar Shah.

In August 2007, Sultan Hassanal Bolkiah paid a visit to the tomb at Santubong while he was in Sarawak.

In 2020, the Sarawak Malaysian Islamic Party (PAS) endeavored to utilize Darul Hana to depict the state of Sarawak as a component of the history for the Sarawak Malays. They contended that the Malay chiefs chosen by the Brooke administration and subsequently the Crown Colony of Sarawak uphold the tradition of Sultan Tengah.
