Is it permissible to perform *Masah* (wiping) over worn-out socks (*Jawrab al-Kharq*)?

Primary text

The consensus holds that socks must possess sufficient thickness and firmness (*safāqah* and *thabūt*) to stand on their own, similar to leather boots (*khuffayn*), for wiping to be valid. Imam Ahmad initially disliked wiping over thin, torn socks (*al-kharq*) possibly due to their lack of self-support. Wiping is only permissible if the sock is thick enough to substitute for the *khuff*, standing upright on the foot without collapsing. The underlying principle is established by the narration of Al-Mughirah, where the Prophet (PBUH) wiped over socks (*jawrabayn*) and sandals (*na'layn*). If the sock requires the sandal to remain in place, the ritual purity (*tahārah*) is nullified upon removing the sandal, because the condition for wiping (the sock's self-support) is then lost, similar to when the foot itself becomes uncovered.
