I travel aproximately 40 miles to work by car everyday between Monday and Friday, leaving the vicinity of my city. I return home each day in the evening. May I shorthen my prayers at work even if I am travelling everyday?


Praise
be to Allaah.  

If a person
travels 100 km from his town, or thereabouts, he may follow the rulings
of travel by shortening his prayers, not fasting, combining his prayers
and wiping over his socks [in wudoo’] for three days, because this distance
is considered to be traveling. The same applies if he travels 80 km
or thereabouts; that is considered to be the distance which dictates
that prayers may be shortened according to the majority of scholars.
