The Kashf al-Mahjub (The Revelation of the Veiled) of Ali b. 'Uthman al-Jullabi Hujwiri. An early Persian Treatise on Sufism

Al-Hujwiri came from Ghazna, now in Afghanistan, then the capital of the mighty Ghaznavid Empire. He was a Sufi mystic who travelled widely in the Middle East and Transoxiana. The Kashf al-Mahjub was probably written in Lahore, where he is buried, not long before his death in about 1074.
