Mīr Sayyid Jalāl ad-Dīn an-Naqwī al-Bukhārī, better known as Jahāniyān Jahāngasht, was a Punjabi Sufi saint from South Asia.

Uch, frequently referred to as Uch Sharīf, is a historic city in the southern part of Pakistan's Punjab province. Uch may have been founded as Alexandria on the Indus, a town founded by Alexander the Great during his invasion of the Indus Valley. Uch was an early stronghold of the Delhi Sultanate during the Muslim conquest of the subcontinent. It is also known as the home for the Naqvi/Bukhari's after the migration from Bukhara. Uch was a regional metropolitan centre between the 12th and 17th centuries, and became refuge for Muslim religious scholars fleeing persecution from other lands. Though Uch is now a relatively small city, it is renowned for its intact historic urban fabric, and for its collection of shrines dedicated to Muslim mystics (Sufis) from 12th-15th centuries that are embellished with extensive tile work, and were built in the distinct architectural style of southern Punjab.
