Moreover, it will be reviewed the manuscript’s codicology aspects in order to reveal the trace of manuscript history well. This study is also hoped to be able to illustrate about the whole basic framework on his sufistic thingking, mainly if it was related to his thought in the past and previous works.This work was originally rewritten in 1868 by Haji Ma’ruf bin Haji Muhammad Hasyim.  This research found that the process of rewriting of this work was carelessly done. The writer found some serious mistakes; the numbering of the pages, miswrite, and some grammatical mistakes. In this work, al-Palembani teaches the basic concept of Tauhid, and then build a doctrine of Wihdat al-wujud on it. - in this case - Wihdat al-Wujud al-Muwahhid. His doctrine was derived from two different concepts; al-Faidh and al-Zhill, which were later combined. The approach used to interpret this teaching was to combine the two different concepts of the scholars from two main streams of sufisms; philosophical and akhlaki mysticism.   Keywords:  Zâd al-Muttaqîn fi Tauhîd Rabb al-`Âlamîn, Syaikh Abdus Shamad  al-Palimbani, Philological Approach
