 For an example of a complex name, one former Prime Minister of Malaysia has the full name Dato' Seri Mohd Najib bin Tun Haji Abdul Razak, where 'Dato' Seri' is a Malay title of honour, 'Mohd Najib' is his personal name (often further abbreviated to 'Najib'), 'bin' introduces his father's titles and names, "Tun" is a higher honour, 'Haji' denotes his father as a pilgrim to Mecca, and 'Abdul Razak' is his father's personal name (often abbreviated to "Razak").The entire name has various shorter forms, like 'Mohd Najib Tun Abdul Razak', 'Najib Tun Razak' and 'Najib Razak').If someone has been on the Hajj, the pilgrimage to Mecca, they may be called Haji for men or Hajjah for women.
