Shaykh Muhyi al-Din Ibn 'Arabi (d. 638)

Muhammad ibn 'Ali ibn Muhammad ibn al-'Arabi, Abu Bakr Muhyi al-Din al-Hatimi al-Ta'i al-Andalusi al-Mursi al-Dimashqi, known as Ibn 'Arabi to differentiate him from Abu Bakr Ibn al-'Arabi the Maliki jurist.

A scholar of Arabic letters at first, then tafsir and tasawwuf, nicknamed al-Qushayri and Sultan al-'Arifin in his time for his pre-eminence in tasawwuf, known in his lifetime for his devoutness to worship, asceticism, and generosity, Ibn 'Arabi was praised by al-Munawi as "a righteous friend of Allah and a faithful scholar of knowledge" (waliyyun salihun wa 'alimun nasih), by Ibn 'Imad al-Hanbali as "the absolute mujtahid without doubt," and by al-Fayruzabadi as "the Imam of the People of Shari'a both in knowledge and in legacy, the educator of the People of the Way in practice and in knowledge, and the shaykh of the shaykhs of the People of Truth through spiritual experience (dhawq) and understanding.
