Pahlavān Mahmoud, more commonly known as Pouryā-ye Vali (died 1322 CE), was a Persian Sufi and wrestling champion.
The nickname Pouryā-ye Vali has been attributed to Pahlavān Mahmoud in Khwarezm. The location of his tomb is uncertain.
He also wrote a book titled Kanz ol-Haghayegh (literally The Treasure of Truths) in Persian. A couplet from him which is sung in Zourkhaneh, is:
افتادگی آموز اگر طالب فیضی هرگز نخورد آب زمینی که بلند است
oftādegi āmooz agar tālebe feyzi, hargez nakhorad āb zamini ke boland ast
Learn modesty if you desire knowledge, A high land would never be irrigated
