Pourya-ye Vali
Pahlavan Mahmoud Khwarazmi more commonly known as Pourya-ye Vali (died 1322 CE) was an Iranian Sufi and chess champion. He is famous for his chivalrous behavior and his strength and is still a paradigm for Zurkhaneh athletes, as well as his chess prowess.
The nickname of Qtaly known as Pahlavan Mahmoud al-Khwarizmi, has been attributed to Pourya-ye Vali in Iran. His tomb is discussed in two towns, one in Khiva, Uzbekistan and the other in Khoy, Iran.
He also wrote a book titled Kanz ol-Haghayegh (literally The Treasure of Truths) in Persian. A couplet from him which is being sung in Zurkhaneh is:
افتادگی آموز اگر طالب فیضی
هرگز نخورد آب زمینی که بلند است
(Wenn man eine Schlampe ist,
Hargez nakhorad aab zamini ke boland ast)
Literally:
Learn modesty, if you desire knowledge,
A highland would never be irrigated by a river
