Crossing Over to the Unseen: Yousef Casewit on Ibn Barrajān
We are delighted to speak with Yousef Casewit of the University of Chicago on the life, times, and thought of Abū al-Ḥakam ʿAbd al-Salām ibn ʿAbd al-Rahmān ibn Abī al-Rijāl Muḥammad ibn ʿAbd al-Rahmān al-Lakhmī al-Ifrīqī al-Ishbīlī, better-known as Ibn Barrajān of Seville (d. 536/1141). Ibn Barrajān was a twelfth-century Andalusian ‘mystic’ – a renunciant philosopher concerned with penetrating the unseen foundations of reality through a Qur’ānic hermeneutic applied to the world itself – whose writings and reputation would go on to influence much later Sufism, particularly via the medium of the great Andalusian sufi Ibn al-‘Arabī. But the spiritual path in Ibn Barrajān’s day and time was a much more free-form and improvisational undertaking than among the later sufis. Casewit argues for a particular stream of esoteric speculation and practice typical of al-Andalus, and also identifies several original contributions from Ibn Barrajān within that Andalusian context.
We discuss:
- The basic life and times of Ibn Barrajān – where and when he lived, what was going on politically, and especially what was going on religio-politically,
- His three extant works – two of Qur’ānic commentary and one on the Divine Names – and of the esoteric moves he makes within them, including:
- The positing of a sub-creating or demiurgic entity known as the ‘Abd al-kullī (the ‘Servant of All’), containing all the essences which are unfolded as particulars in the world,
- And an elusive spiritual practice, the i‘tibar, ‘crossing over’, a form of contemplation which might lead to insights into the divine nature latent in the creation, or might perhaps make higher claims to a more, shall we say ontological transformation of the human aspirant toward apprehension of god’s nature,
- Ibn Barrajān’s relationship to the larger movement known as ‘sufism’, to his particular Andalusi sufi milieu, and his originality within both of those larger contexts,
- And the undeniable fact that Ibn Barrajān predicted the retaking of Jerusalem by Saladin almost to the minute, and what we are to make of that.
