Mizan married
Sultanah Nur Zahirah on 28 March 1996 in Kuala Terengganu. The royal couple have two sons and two daughters: •
Her Highness Tengku Nadhirah Zahrah, the Tengku Puteri Utama Raja (b. 18 December 1996) •
His Royal Highness Tengku Muhammad Ismail, the Crown Prince (b. 1 March 1998) •
His Highness Tengku Muhammad Mua′az, the Tengku Sri Setia Mahkota Raja (b. 22 December 2000) •
Her Highness Tengku Fatimatuz Zahra’, the Tengku Puteri Daulath Raja (b. 19 April 2002) After Sultan Mizan was elected as the
Yang di-Pertuan Agong, he appointed Tengku Muhammad Ismail, then aged eight, as regent on 12 November 2006. Because of Tengku Muhammad Ismail's young age, a three-member Regency Advisory Council was established to discharge his duties for him. The council's members were Tengku Baderulzaman, Sultan Mizan's younger brother, Tengku Sulaiman Ismail, Sultan Mizan's uncle, and former Federal Court judge
Dato' Abdul Kadir Sulaiman. He was proclaimed as regent during a ceremony on 12 December. Upon reaching
Mukallaf (13 years of age), the Islamic age of responsibility, and according to
Sharia law and the constitution of Terengganu, Tengku Muhammad Ismail became able to discharge his duties himself. However, the Sultan formed another council, Majlis Perwakilan Pemangku Raja, to perform the Regent’s duty while he was away from Terengganu pursuing his studies. This second and current council is headed by Tengku Mustafa Kamel, another of Sultan Mizan’s younger brothers, together with former Regency Advisory Council members Tengku Sri Laksamana Raja Tengku Sulaiman Ismail and Dato' Haji Abdul Kadir Sulaiman. During his younger days, Sultan Mizan was a keen
footballer. He is currently active in
golf,
endurance riding and
scuba diving. In addition, the Global
Taekwondo Federation (GTF) awarded Mizan an Honorary 7th Degree
Black Belt in recognition of his active participation in the sport. ==Honours==
