analyzing the rule of emanation from the simple one ‎in islamic philosophy: from interpretive challenges to ‎transcendent elucidation

one of the most crucial philosophical rules and a cornerstone of rational principles is the nothing but the one emanates from one. this article, employing a library research method for data collection and an analytical and descriptive approach for data analysis, aims to accurately explain this rule. it also seeks to address the arguments of those who oppose the rule, as they haven't correctly grasped its underlying premises. by carefully considering these premises, we find that the unity referred to in the rule is not numerical unity, but rather true, real, and original unity. furthermore, the one signifies a simple entity from all aspects and dimensions. emanation implies direct emanation and illuminative emanation, and homogeneity refers to shadowy homogeneity . with these introductions, the meaning of the rule becomes clear: from the one that is simple in all respects (basīṭ min jamī' al-jihāt), by virtue of the principle of shadowy homogeneity (senkhīyyat ẓillīyyah), and without an intermediary and with an illuminative relation (iḍāfah ishrāqiyyah), nothing but the one emanates.. indeed, according to the elucidations of mystics and transcendent philosophers (muta'allihīn), the single effect  that emanates from the utterly simple one (god) is precisely what they call expanded existence or expanded grace.
