Abstract
The 'Al Emla-fi-eshkalat el- Ehya' is an unknown book belonging to Ghazzali, in which he has explained some of the terms existing in Ehya-ol-Olum. In this book, he has also explained some mystical terms. Also Ibn-e-Arabi’s writing, that is, Fotuhat-al-Makkieeh has entered in the- so called- field of lexicography. This was owing to the fact that such a kind of attitude toward “Fotuhat-al-Makkieeh” had forced him to extract, arrange, and subsequently describe some of the terms. Consequently, Both Gazzali and Ibn-e-Arabi came to field of lexicography through writing their books. In this research, these books are considered according to their lexicographical features.
