A true pilgrimage is really a journey within
I agree that Hajj is a journey within a Muslim, but there are parts of Hajj that will greatly take a physical toll on a pilgrim. I have already described how each event is both a physical and mental challenge but I do also believe that some Muslims may be used to the hot climates that may be faced. This would not be seen as a challenge to them. Also a Muslim may do a lot of exercise so therefore some vents may not be a great deal of effort for such a person. The same would apply for the Stand, in some cases one pilgrim may be used to standing for long hours in the heat.
