Q498 :I saw some people, sportsmen and soldiers,
offering their prayers in mosque without taking off their shoes. Is it
permissible?
A498 : Yes, it is. The only condition is that which
applies to whatever we wear when we pray, namely, that it has not been
contaminated with impurity. This means that if you are certain that you
have not stepped over an impurity, you may offer your prayers wearing
your shoes. The other point of importance when you do this in a mosque
is to make sure that you do not bring any dirt into the mosque. You
have to maintain the mosque clean.
