The eminent Sufi theologian Khwaja Abdullah Ansari has written numerous works on Islamic mysticism and philosophy in Persian and Arabic.

His influential Munajat Namah (literally 'Litanies or dialogues with God') a collection of mystical prayers in rhymed prose, gains the greatest renown as a masterpiece of Persian literature.

After his death in 1088, many of his sayings that had been transmitted by his students along with others that were in his written works will be included in the Tafsir of Maybudi, Kashf al-Asrar (’The Unveiling of Secrets’).

This is among the earliest complete Sufi Tafsirs of Quran and will been published several times in ten volumes.
