He is among the heroes who disappeared (or died) in snow during Kay Khosrow's ascent to heaven. Beside Gostaham, four other Iranian heroes also disappeared in this accident. There's a mountain pass named Molla-ye Bižan in the Kohgiluya district where as believed by locals, is where the heroes disappeared. He was also mentioned in other sources. The unknown author of Mojmal al-tawārikò wrote what he was called "rāst-andāz" (sharpshooter) and "saḵt-kamān varāz" (sharp-shooting paladin).
