It was discovered in Hulu Terengganu in the 14th Century, in 1303, as stated by Prof. Syed Naguib Al-Attas as cited in The Genius of Malay Civilisation (Asmah Haji Omar 2003:50).
The stone tells of Islamic regulations and provides an early evidence of Islam in Terengganu and vicinity. Many have not seen the stone but have heard about it. I saw the replica stone for the first time at Muzium Islam in Kota Bharu, Kelantan. The real stone is at Muzium Negeri Terengganu.
This is a black stone cut into an irregular pedestal with 4 flat surfaces. It has an unusual geometry, much like a tall columnar headgear. There is Jawi writing on each roughly cut surface. Since this is a replica stone, the Jawi inscription appears on the surface and not cut into the stone surface. The real stone has Jawi inscription cut into the stone surface (dipahat) and the stone has the original granite surface, like that of batu tumbuk and batu giling. It is also known as Batu Berukir Terengganu as the Jawi inscriptions are inscribed onto the stone surface.
