Ruling 258 — Purification (Ṭahārah)

Wiping performed on socks or shoes is invalid. However, if one is unable to remove his socks or shoes on account of severe cold, or fear of thieves or predatory animals etc., then the obligatory precaution is that after he has wiped on his shoes or socks, he must also perform tayammum. If it is a matter of taqiyyah,[1] it is sufficient if he only wipes over his socks or shoes.
