For example, in May 2025, in Iran an international conference entitled The Logical Thoughts of Mullah Abdullah Yazdi: Comparative Analysis, Innovations, and Influence in the Tradition of Islamic Logic was held. Noor Farghan Instiute has listed the thoughts of Yazdi as a research priority for the doctoral and master's education on his intellectual thought.
