Mention of wiping over the leather socks in matters of creed

Question:
And the Shaykh’s small point: Did the Companions disagree on a matter of fiqh? If that is true, how can this issue be classified as a matter of creed as long as the Companions disagreed on it?

Answer:
It is not known that the Companions accepted wiping over the leather socks; rather, it is a matter of consensus (ijma') among the people of the Sunnah and the consensus. The only ones who opposed this were the Shi'ah, specifically the Rafidah. The scholars mention wiping over the leather socks in creed in order to refute the Rafidah, who disagree on this point. Even though this issue is a matter of fiqh, a branch issue, they mention it in the context of opposing the Rafidah innovators who do not see the validity of the sa'y or the verification. Thus, they are contrary to the Sunnah of the Messenger (peace and blessings be upon him), contrary to what was mass-transmitted from the Messenger (peace and blessings be upon him). This is the reason for its mention in the creeds.
