Sharif Ali was a descendant of Imam Hasan ibn Ali. In addition, he served as the Emir of Mecca, and was entitled Al-Amīr Ash-Sharīf ʿAlī bin Ash-Sharīf ʿAjlān bin Ash-Sharīf Rumaithah bin Ash-Sharīf Muḥammad Abū Numāʾī Al-Awwal (ٱلْأَمِيْر ٱلشَّرِيْف عَلِي بِن ٱلشَّريْف عَجْلَان بِن ٱلشَّرِيْف رُمَيْثَة بِن ٱلشَّرِيْف مُحَمَّد أَبُو نُمَائِي ٱلْأَوَّل). The Sultan was also an ancestor of the Brunei, Sambas and Sulu royal families.^[1]

As Sultan,^[3] Sharif Ali made several changes closely linked to Islamic Law, including basing the administration's rule on the law, straightening the direction of the Qiblah, and creating a law prohibiting people from eating pork. The penalty for violating this law was death. Besides religious affairs, Ali's administration was responsible for a number of legacies including creating an emblem and banner – the "Tunggul Alam Bernaga" – which symbolised the dignity of Brunei and the Crown of the Sultan. These artifacts continue to be utilized by the current Sultanate. The mausoleum of Sharif Ali is situated close to the Brunei Museum and the mausoleum of Sultan Bolkiah, the 5th Sultan of Brunei Darussalam. Sultan Sharif Ali's mausoleum was built as a tribute and recognition of his contribution to strengthening the Islamic foundations of the Sultanate. In addition to building Ali's mausoleum, Sultan Hassanal Bolkiah (the 29th Sultan of Brunei) also built a grand mosque named "Masjid Sultan Sharif Ali", as an appreciation for his contributions to Islam. The mosque, which was inaugurated in 1986, is located in Kampong Sengkurong; approximately 16 km (9.9 mi) from Bandar Seri Begawan. Several institutions in Brunei also carry Sultan Sharif Ali's name, which include Sultan Sharif Ali Secondary School in Salambigar, Jalan Muara, and Sultan Sharif Ali Islamic University. The royal symbol's origin came from the World's largest seed, which is called "coco de mer."^{[citation needed]}
