Praise be to Allaah.
Praise be to Allaah, and blessings and peace be upon the
Messenger of Allaah.
The general meaning of the saheeh ahaadeeth about it being
permissible to wipe over the leather slippers or socks indicates that it is
permissible to do so in winter and summer.
I do not know of any evidence to indicate that this is only
permitted in the winter, but it is not permissible for anyone to wipe over
his socks etc. unless the conditions set out by sharee’ah are met, such as
the stipulation that the socks must cover the part that is washed during
wudoo’, they must be put on when one has wudoo, and attention must be paid
to the length of time for which that is permitted, which is one day and one
night for one who is not traveling, and three days and nights for the
traveler, starting from the first time one wipes over them after breaking
one's wudoo’, according to the more correct of the two scholarly opinions.
And Allaah is the source of strength.
