Her Royal Highness the Crown Princess of Brunei Darussalam, Yang Teramat Mulia Paduka Seri Pengiran Anak Isteri Pengiran Anak Sarah binti Pengiran Salleh Ab Rahaman was born on 9th April 1987 as Dayangku Sarah at the Raja Isteri Pengiran Anak Saleha Hospital in the capital of Brunei Darussalam, Bandar Seri Begawan.
Princess Sarah is the third and youngest child of Pengiran Salleh Ab Rahaman bin Pengiran Haji Damit and Rinawaty binti Abdullah @ Suzanne Rahaman Aeby. Her mother is Swiss. Her two elder brothers are Awangku Irwan and Awangku Adrian.

At the age of 17, Sarah married the Crown Prince Al-Muhtadee Billah in an elaborate wedding ceremony at the Nurul Iman Palace in Bandar Seri Begawan on 9 September 2004. After the initial ceremony, the Prince and Princess rode around Bandar Seri Begawan in the back of a specially customized gold Rolls Royce. Despite the rainy conditions, thousands of Bruneians lined the streets of Jalan Sultan, among others, togreet the newlyweds. On 17 March 2007 at 3.50 pm, Prince Billah and Princess Sarah welcomed the birth of their first child and likely future heir to the Brunei throne, a son named Abdul Muntaqim. In honor of the birth of the prince, a 19-gun salute was fired from the cannons on the grounds of Istana Nurul Iman, the official residence of the Sultan of Brunei. The gun salute is traditionally carried out to mark the births of immediate members of Sultan's family and serves as an announcement of a royal birth to the Bruneian people.
