. Please elaborate on women doing Zip Lining with their purdah on. They further are proud about it and brag about it. The men have to Zip you up and touch you and manhandle you. Also some Zip Lines when you come to the end they hold you to break the fall. 
Meaning of Zip lining: to ride for recreation along a suspended, inclined cable equipped with a pulley and a harness:
“We ziplined for more than two hours through the rainforest.
ZIP Lining is when they tie and harness someone between their legs and let them Zip line from one cliff to a lower cliff. Normally males tie up females between their legs.”
Can this ever be permissible for Muslim women?
A. “Ziplining” as described by you is absolutely appalling for a Muslim woman. It is an act of ZINA. A woman who subjects herself to such zina treatment is like a prostitute. In fact she is a ZAANIYAH. Only women with prostitute tendencies and whose Imaan dangles on a thread will allow themselves to be so disgracefully mishandled by males. It is in fact zina.
A husband who allows his wife to be zina-handled or even taken on such evil shaitaani joy rides in cable trollies is an evil dayyooth. He is utterly bereft of haya and Ghairat (honour). The excursion from beginning to end is haraam. Both the husband and his wife are under the Curse of Allah Ta’ala during this evil, haraam excursion in which the woman is zina-handled.

A zip-line, zip line, zip-wire, or zip-power-line[1][2][3][4][5] is a pulley suspended on a cable, usually made of stainless steel, mounted on a slope. It is designed to enable cargo or a person propelled by gravity to travel from the top to the bottom of the inclined cable by holding on to, or being attached to, the freely moving pulley. It has been described as essentially a Tyrolean traverse that engages gravity to assist its speed of movement.[5] Its use is not confined to adventure sport, recreation, or tourism, although modern-day usage tends to favor those meanings.[6]
