In 1202, the Andalusian mystic Ibn Arabi developed a profound philosophical framework known as 'Wahdat al-Wujud' or Unity of Being. This concept posits that all existence is a manifestation of the Divine, emphasizing the interconnectedness of all things. Ibn Arabi's ideas significantly influenced Sufi thought and Islamic philosophy, promoting a deeper understanding of spirituality and the nature of reality that resonates with seekers of truth across cultures.

Ibn Arabi's development of Sufi metaphysics became foundational for Persian, Urdu, and Turkish Sufi ghazals. His complex allegories of divine presence transformed romantic imagery, influencing poets such as Rumi and Ghalib, who infused their works with spiritual depth and longing.
