Born on 26 May 1987 at Susuka, Choiseul Province, Solomon Islands, Sultan Hakim Nooruddin Apani'ai has been the Sultan (Ruler) of Rau'ahu (Ārai Peninsula) since 2018. He is the 5th ruler of the island including Cordoba (Tawaroto) and Istanbul (Āhu'i) — on the mainland — in the traditional reckoning.

By religion, Hakim was a Roman Catholic prior to his acceptance of Islam in year 2000 when he was 13 years old. In year 2005, at the age of 18, he embraced Islam Ahmadiyya.

Sultan Hakim was born as the son of Al-Kindi (Michael Iuhaniramo), a descendant of a Great warrior, Apani'ai Paina, through his grand son, Tahisimae Joseph (died 1950s). This branch of the Rau'ahu royal dynasty is named Hakimids Dynasty, after Hakim, the Sultan. The Rau'ahu Sultanate lapsed in early centuries (year ?) with the demise of the last ruling Sultan, his distant relative ancestor, Haimā'i Paina, during the battle of Hanuahansia. However, the monarchy was revived and replaced by Sultanate system as a cultural institution in 2018 when Hakim Nooruddin Apani'ai was enthroned in distressed outer circumstances. Sultan Hakim was enthroned on 26 May 2018 (28 Dhu al-Hijjah 1436 AH).

Apart from his ceremonial duties, the Sultan is also a member of the Ahmadiyya Muslim Association Solomon Islands, representing Small Mala'ita Jama'at (Muslim Community) since 2005. He has strongly promoted the appointment of a Sultan and firm establishment of Sultanate system as a cultural institution among his descendants, present and future.

Hakim completed his primary education at Ta'aru Primary School, South Mala’ita, in 2004, after which he went to Honiara, the Capital city of Solomon Islands, to do his secondary level: Tuvaruhu SHS (2005–2007), Vura SHS (2008–2009), and Honiara SHS (2010). It was in his first year (Form 1, i.e, year 7), in 2005, that he embraced Islam Ahmadiyya with the help of his elder brother, Dr. Muhammad Adam. After completing his Science study (Biology, Physics and Chemistry) in 2010, Hakim was then appointed by the late Amir, Mahmood (the national president and Missionary In-charge for Jama’at Ahmadiyya Australia), to be the Imam (religious leader) for the Ahmadiyya Muslim Community, Solomon Islands. On 18 August 2013, Hakim travelled to Ghana, West Africa, to further his study in the field of Islamic Theology. He has undergone successfully a 3–Year Course of Theological studies, from August 2013 to August 2016.

After completing his study at the Islamic University of Theology in 2016, Hakim returned to Solomon Islands and is posted as Missionary In-Charge for the Ahmadiyya Muslim Community of Solomon Islands. He had served the community for over two years (September 2016 to December 2018), after which he left.

After he had been removed from his missionary work in late December 2018, Hakim left in anger and, after declaring himself as the first Sultan on 26 May 2018, established his own dynasty, the Hakimids Dynasty. His 2005 dream of creating a future family dynasty has now come into shape; he initiated it by exercising authority, based on Islamic principles, over his own family. The dynasty is continuing up to date.
