Shaykh Bin Baz was asked:
If I put on a pair of socks while being Tahir (ritually pure) after the Fajr (Dawn) Prayer and wipe over them when performing Wudu’ (ablution) for the Zhuhr (Noon) Prayer, then I wear another pair of socks while being Tahir, is it permissible to wipe over the second pair of socks? Does the duration of permissibility of wiping over socks apply to the first or second pair of socks? Please, advise! May Allah reward you!
“It is unobjectionable to wipe over another pair of socks if you put it on while in a state of Taharah (ritual purification). The duration of the permissibility of wiping over socks will then apply to the newly put on socks as they are worn while in a state of Taharah. This is analogical to the case when someone puts on socks or Khuffs (leather socks) while in a state of Taharah after wiping over a splint. May Allah grant us success.” End quote. [Reference]
