It is said that Jahsh emigrated to Abyssinia and joined Sa'd ibn Abi Waqqas in overseas preaching. “The Chams of Cambodia ascribe their conversion to one of the fathers-in-law of Muhammad” named "Geys" (Jahsh). “The Chinese Muhammadans have a legend that their faith was first preached in China by a maternal uncle of the Prophet, and his reputed tomb at Canton is highly venerated by them.” What later generations misconstrued as the tomb of "Geys" appears to have been a mausoleum dedicated to his memory in Hami, 400 miles east of Ürümqi in Xinxiang.
