Based on many papers/books written about Islam in Champa and Cambodia, till now, there are only small amount of it discusses about the Islamic intellectual written heritages, such as Arabic Kufic inscriptions and Arabic/Malay/Cham manuscripts. I am referring traditionally to the discussions about Islamic intellectual written materials by Ravaisse (1922), Lafont et. al. (1977) and Po Dharma (1981). Most of writings later on were based on their initial works, some even easily copying their ideas.
