Mīr Sayyid Makhdoom Jalāl ad-Dīn an-Naqwī al-Bukhārī / Naqvi Al Bukhari (Persian: میر سید جلال الدین النقوی البخاری; 1308-1384), better known as Jahāniyān Jahāngasht (Persian: مخدوم جہانیاں جہان گشت), was a Punjabi Muslim[1] Sufi saint from South Asia.

His father, Sayyid Aḥmad Kabīr, was the youngest son and chosen successor of Jalaluddin Surkh-Posh of Bukhara.

He travelled to many countries including Kāzarūn, Egypt, Syria-Palestine, Mesopotamia, Balk̲h̲, Buk̲h̲āra, K̲h̲urāsān, and visited Mecca 36 times in his life.

Muḥammad b. Tug̲h̲luḳ appointed Jalāl al-Dīn as S̲h̲ayk̲h̲ al-Islām and was granted forty k̲h̲ānaḳāhs in Sīwastān, but left for the Ḥajj.

Jalāl al-Dīn also accompanied the king on his campaign to Ṭhaṭṭā and was a major influence on Fīrūz's religious policies.
