Exegesis of the saying of Allah the Exalted: “And your feet to the ankles” in the verse of ablution

Question:
Honorable Shaykh, may Allah grant you success, how do we respond to the Rafidah who wipe their feet, citing the verse and saying, "I did not say 'do not wash them' as is the case with the face and the hands?"

Answer:
The well-known and recognized reading is the nominative case (rafa'), “and your feet to the ankles,” which is coordinated with “and your hands to the elbows.” This is the well-known and recognized reading.
As for the genitive case (jarr) reading , the intended meaning of wiping the feet is washing, because washing is sometimes called wiping. This is evidenced by the action of the Prophet (peace and blessings be upon him). The action of the Messenger is what explains and clarifies the Qur'an. He (peace and blessings be upon him) explained this as being a wash like the others. The scholars of Arabic grammar say that this genitive case is solely for proximity, solely for proximity. Because the feet are adjacent to the wiping of the head, the genitive case was applied to them due to proximity, and this is not to rule on both with the same ruling as the one. This is called proximity (majawarah), and it is not a case where the ruling is the same for both; the ruling is different.
Some scholars, such as Ibn Jarir and others, hold that the genitive case reading is applied when there is a covering on the feet, meaning if there is a covering on them. This is not far-fetched, and I think the Shaykh al-Islam is referring to this.
