This dissertation aims primarily at presenting the critical edition of two works: AlWāridāt wa’l-Taqdīsāt and Sharḥ al-Asmā’ al-Arba‘īn. The first text is for the first time published in its entirety. Some of its disparate fragments (around the third of the entire size in total) have been already printed in original Arabic or in Persian and French translations but were not subjected to serious critical editing based on more than one original manuscript. As far as the second is concerned, which has the character of a free form and multiple variants extant in the numerous manuscripts I cannot exclude the possibility that some of them could 7 have been issued uncritically under another title, however I do not own any substantial knowledge in that matter, except the single prayer (Du‘ā’ Idrīs) that is the base of the commentary and was published at least three times. What I hope is that for the first time various variants of the commentary (Sharḥ) have been presented simultaneously and in the form of critical edition. This dissertation contains also the critical edition of additional seven short texts of Al-Suhrawardī that are found in the manuscripts related to Al-Wāridāt wa’l-Taqdīsāt.
