The book never, even once, mentioned Wali Songo, a religious propagator in their era, science development and cultural wealth during the Wali Songo era. Such as literary works, music art, fine art, art shows, beacon art design, architectures, philosophies, Sufism, law, state administration, ethics, astrology, calendar system, and medical science development in the Wali Songo era and after that era.
It reaches the climax when Zainal Abidin Bin Syamsudhuha publish his book entitled Fakta Baru Wali Songo (New facts about Wali Songo), which contains unilateral and unobjective assumptions toward Wali Songo. The analysis of the book relies on a lot of inaccurate resources to conclude that Wali Songo never exists. In one of its chapters, this book explained the Islamification of Java, the build of the Muslim community, Java origin religion, Java culture and tradition. In the last section of the book, the writer attempted to argue the existence of Wali Songo with an interesting sub-chapter: New facts about Wali Songo!
Eventually, both books arguments can be disputed by the advent of another well-known legendary book. Inside Historiografi Jawa, it is mentioned that in the early 14th century, two brothers were coming from Champa, the elder brother name is Ali Murtadho, and the younger one is Ali Rahmatullah, together with their cousin Abu Hurairah they took a trip to Java.
With the help from their aunt, Darawati, who was married by Sri Prabu Kerta Wijaya, the king of Majapahit (1447-1451), Ali Rahmatullah was chosen to be an imam in Surabaya. His elder brother was appointed to be King Pandhita in Gresik. Starting from this Champa family, the Islam dakwah began to spread in Majapahit territory. Especially after their descendants, relatives, and students began to do dakwah systematically through the dakwah network, the so-called Wali Songo. (Introduction Pg.VI)
On the other hand, Agus Sunyoto cites the Historiograf Jawa, Cirebon, dan Banten by depicting every figure of Wali Songo with a sacred story. Each of the figures was illustrated to have the superhuman ability. This beautiful and fascinating karomah attracted a lot of people from society to convert to Islam. Meanwhile, history fact shows that after the Islam dakwah done by Wali Songo, Islam starts to develop in the inhabitant community successfully. Tome Pires, a medical expert who became the Portugal ambassador in China, visited Java in 1515. According to the Suma Oriental book, the territory of North Java coastwise is managed and controlled by Muslim dukes. The same fact was witnessed by A Pigafetta, who visited Java in 1522.
