When Should the Feet be Washed and When Should they be Wiped?

As for the feet, they are washed and wiped over. Its for this reason, the recitation of the saying of Allah: “wa-Arjulakum “ (meaning of which: And your feet) has come in the noble Qur’an in two ways, in one recitation: “Wa-Arjulikum” and in another: “Wa-Arjulakum”. As for the recitation, “Wa-Arjulikum” it is a conjunction upon the saying of Allah (meaning of which): "Wipe your heads and feet", meaning: And wipe your feet. As for (the recitation in) the state of Nasb (having fathah) “Wa-Arjulakum” it is a conjunction upon the saying of Allah (meaning of which): "Wash your faces", meaning: And wash your feet. But, when should the feet be wiped? The feet should be wiped when one wears socks or khuff (similar footwear). Al-Jawarib (socks) are those made of cotton, wool, or it's like. Al-Khuff are those made of leather or from that which is similar to it. He wipes on them, however, with four conditions.
