Malik Ibrahim (died 7 April 1419), also known as Sunan Gresik or Kakek Bantal, was the first of the Wali Songo, the nine men generally thought to have introduced Islam to Java.
[Notes 1] The most generally accepted history, supported by a reading by J. P. Moquette of the inscription at Ibrahim's grave, identifies him as having come from Kashan, Persia (modern-day Iran).
[6] Dutch writer and researcher Martin van Bruinessen describes Jumadil Kubra, Malik Ibrahim among all their students are followers of Kubrawiyyah .
According to this version, Qubro stayed in Java while his sons went abroad for dakwah: Ibrahim went to Champa (in modern-day Vietnam), while his brother went to Pasai in northern Sumatra.
[5][14] Ibrahim landed at Sembalo, Learn, Manyar (9 kilometres (5.6 mi) north of modern-day Gresik) in the late 14th century, where he became acquainted with the local people.
[15][16] He began trading out of the harbour, dealing equally with people from different castes - social strata based in the dominant Hindu religion.
After journeying to Trowulan to meet the king of Majapahit, he was granted a landing on the outskirts of Gresik which was used for preaching; Ibrahim also founded an Islamic boarding school there.
[4] Malik Ibrahim's grave, which is without a headstone,[18] is a common destination for pilgrims, who read the Qu'ran and the life of Muhammad; they also partake in a dish unique to the area, harisah rice porridge.
By comparing the marker with others found in the Pasai Kingdom, historians such as Brian Harrison and G. H. Bousquet have suggested that the spread of Islam in Indonesia originated in India.
