 Suhrawardi’s criticism of the essence-existence distinction had an impact on later discussions, namely those of Ibn Kammuna (d.1284) (Eichner 2010), Athir al-Din al-Abhari (d.ca.1265) and al-Katibi al-Qazwini (d.ca.1276) (Eichner 2012). Later, Mulla Sadra (d.1636) notes Suhrawardi’s confusion between the concept of existence and the reality of existence and replaces his notion of light with the notion of being, blending Avicenna’s ontology of contingency with his ishraqi hierarchy of lights (Rizvi 1999, 225).
