Abū Zakariyyā Muḥyi'd-dīn Yaḥyā ibn Sharaf an-Nawawī (631 AH/1233 CE - 676 AH/1277 CE) was an exemplary scholar of the hadith, Ash'arī kalām and the Shāfi'ī madhhab, noted for his commentary on Ṣaḥīḥ Muslim, his collection of Forty Hadith, the Riyāḍ aṣ-Ṣāliḥīn, the Adhkār, which is a collection of dhikr and du'ā from the Qur'ān and the hadith, and a number of other significant works.
The Garden of the Gnostics (Bustān al-'Ārifīn) is Imam an-Nawawī's work on taṣawwuf, drawing as is his wont on the Qur'ān, with careful choice of hadith, and the sayings of the first generations (salaf) and eminent later people.
