His reign was under attacks of the Dutch East India Company (VOC) which took advantage of Tengku Alam (later became the fourth Sultan) as a shield.

[2] The daughter of fourth Sultan, Abdul Jalil Alamuddin Syah, Badriyyah was married to Sayyid Uthman.

He was a son of Sayyid Ibrahim Panjang Hidung, who was the husband of Siti Hitam, the daughter of Sayid Abdul Majid, a descendant of Ba'alawi.

Almost all the Sultans of Siak from lineage of Sayyid Ali adopted the title "Syaifuddin" to signified their Arab ancestry.

His son, Syarif Hashim Abdul Jalil Muzaffar Shah was then raised to the throne during period 1889–1908.

[2] Post Anglo-Dutch Treaties of 1870–71, the colonial government created the Siak Residency in 1873, which covers the entire northeast coast of Sumatra to the sultanate of Deli.

[6] In 1889, the 11th sultan, Syarif Hasyim Abdul Jalil Syarifuddin built a Moorish-style palace 120 kilometres (75 mi) upstream of the Siak river in Pekanbaru.

In the architecture of the palace there are European influences that blend harmoniously with the Malay and Moorish elements, with the furniture was even brought from Europe.

The palace contains royal ceremonial objects, such as a gold-plated crown set with diamonds, a golden throne and personal objects of Sultan Syarif Qasyim and his wife, such as the "Komet", a multi-centennial musical instrument which is said to have been made only two copies in the world.

It is said that while the Sultan and his dignitaries were discussing the project, suddenly appeared a white dragon on the surface of the river Siak.

To the right of the main gate of the Syahabuddin mosque is the royal family cemetery, with its decoration of Muslim art.
