The final manuscript, Sloane 2645, is a volume in Arabic with interlinear commentary in Javanese in Arabic (pegon) script, containing the Mukhtaṣar, ‘Commentary’, by the 16th-century scholar from the Hadramaut, ‘Abd Allāh bin ‘Abd al-Raḥmān Bā Faḍl. This work, the Muqaddima al-ḥaḍramiyya, 'Hadrami Introduction', also entitled Masā’īl al-ta‘līm, 'Questions for instruction', is an important text of the Shafi‘ī school of law, which was widely used throughout the Indian Ocean littoral spreading out from Yemen to East Africa and Southeast Asia. This well-preserved manuscript, copied in 1623, is one of the earliest dated manuscripts written on dluwang, Javanese paper made from the beaten bark of the mulberry tree.
The writing of the date 1545 (AD 1623/4) in numerals is of some interest. It shows very clearly the standard Indian form of the numeral 5, like a reversed B, used throughout Southeast Asia until the late 19th century, but barely recognized any longer, having long been displaced by the standard Middle Eastern form of the numeral 5, ۵. More intriguing is the use of a system of dots indicating the unit place: the 1 is followed by three dots indicating thousands, 5 is followed by two dots indicating hundreds, 4 is followed by one dot indicating tens, and finally 5 is in the unit of ones. Exactly the same protocol is utilised in a decorative roundel found at the start of the manuscript, reproduced below.
