Does the reading of kasr in the verse of ablution imply adjacency, or the prohibition of extravagance, or the state of wearing leather socks?

Question:
May Allah reward you, Your Eminence, father. The questioner says: In the word of Allah the Exalted in the verse of ablution , it is read with a kasr on the lam in "al-rijl" (the feet). The question is that some of the exegetes have explained the reading of kasr as kasr of adjacency, while others said that the intent is to indicate not to be extravagant in washing the feet with water, but rather to reduce the water until it is as if one is wiping them. It was also said that the reading of kasr is to be understood in the state of having leather socks on the feet. So which of these explanations is most correct regarding the reading of kasr?

Answer:
They are all correct, and praise be to Allah. In them is a refutation of the Shi'ah who say that the reading of kasr is for wiping: "Wash your heads and your feet," meaning "and wipe." They wipe their feet and do not wash them. May Allah keep us safe. The verse is to be understood as adjacency, that this is from the kasr of adjacency because what came before it is in the genitive case.
As for the ruling, the two feet are washed, and the one who washes them in this manner is following the Sunnah of the Messenger of Allah (peace and blessings be upon him). Did he (peace and blessings be upon him) wash his feet? Yes, in the authentic hadiths and in the description of the ablution of the Messenger of Allah (peace and blessings be upon him), it is stated that he used to wash his feet, unless he had leather socks on them, in which case he would wipe over them. And the Messenger of Allah (peace and blessings be upon him) is the explainer of the Qur'an and the clarifier of the Qur'an. Yes.
