Kulliyyāt-i Mīrzā Ḥusayn b. Yaʿqūb Shāh Patrawī contains the collected poems of Ḥusayn b. Yaʿqūb Shāh Patrawī (known as Mīrzā Ḥusayn, b. 1047/1637). He was one of the most learned dāʿīs (missionaries) and authors of the Nizārī Ismaili tradition in Iran at his time. The information available about him is limited, and most of it is taken from his own poems and treatises. Poems by his father, Yaʿqūb, and his grandfather, Ṣūfī, show that they were learned people who occupied the highest positions in the leadership of the Ismaili community in Khurāsān. According to the sources, Mīrzā Ḥusayn was born into a family that had held the position of dāʿī or religious teacher in the Ismaili daʿwa organisation for several generations. It seems that this family first lived in Patraw in the Khwāf district near Herat and Mashhad. Despite dying young (after 1072/1661), Mīrzā Ḥusayn authored many works of prose and poetry. These works show that he was an eloquent poet and orator. His most famous work is Tazyīn al-majālis which was written in both prose and poetry on four important festive occasions in the tradition of Iranian Ismailis. He also wrote several qaṣīdas in praise of Imam Khalīl Allāh II. There are many other poems in the forms of mathnawī and qaṣīda by Mīrzā Ḥusayn that have been found in Ismaili manuscripts and were probably part of his Dīwān. Unfortunately, his Dīwān has not survived in its complete form. This edition includes all works identified to date by this author. However, it cannot be ruled out that after more research, further works by this author may be found.
