Ma Mingxin (1719–1781) (simplified Chinese: 马明心、马明新; traditional Chinese: 馬明心、馬明新; pinyin: Mǎ Míngxīn; Wade–Giles: Ma Ming-hsin) was a Chinese Sufi master, the founder of the Jahriyya menhuan (Naqshbandi Sufi order).
Ma Mingxin's Arabic given name was Ibrāhīm. After returning to China from Arabia he started calling himself 'Azīz.
He was also called Muhammad Emin (Arabic: محمد أمين). Followers of the Jahriyyah sometimes refer to him by the title of Wiqāyatullāh (Arabic: وقاية الله)
A Chinese-speaking Muslim from Gansu, Ma Mingxin spent 16 years studying in Mecca and Yemen. He was a disciple of a Naqshbandi Sufi teacher named 'Abd al-Khāliq, who was a son of az-Zayn b. Muhammad 'Abd al-Baqī al-Mizjaji (1643/44-1725), originally of Mizjaja near Zabīd, Yemen. Az-Zayn, in his turn, had studied in Medina under the famous Kurdish mystic Ibrahīm ibn Hasan al-Kūrānī (1616–1690), who was known for advocating the vocal (rather than silent) dhikr (invocation of the name of God).
After returning to China in 1761, Ma Mingxin founded the Jahriyya menhuan (order) (哲合忍耶; Zhéhérĕnyē) - the second Naqshbandi order in China after Ma Laichi's Khufiyya. In opposition to the "silent" Khufiyya Sufis, and following al-Kurani's teaching, Jahriyya adherents advocated vocal dhikr, which is reflected in the name of their school (from Arabic jahr, "aloud"). Ma Mingxin also opposed the emphasis that the Khufiyya members placed of the veneration of the saints, construction of grandiose elaborately decorated mosques, and the enrichment of religious leaders at the expense of their adherents.
