Were the foundations of Ibrahim (peace be upon him) known or not?

The questioner : You mentioned in the hadith you presented, which is the statement of the Prophet (peace and blessings be upon him) Then, when he was commanded to pray facing the Hajar al-Aswad. The question I actually want to ask, and the answer may be known to many, but we need some clarification and detail. This question seems to hint, or the hadith almost explicitly states, that the foundations were apparently passed down from generation to generation since the time of Ibrahim (peace be upon him). This is the first part of the question. As for the second part, I also seem to hint from the hadith that the construction of the House, which Ibrahim and Isma'il (peace be upon them) built or established its foundations, seems to have been a determination of the foundations by divine revelation. We need some clarification and detail regarding this question in both parts. May Allah reward you.

The Shaykh : As for the fact that the foundations upon which the Ka'bah was built by Ibrahim (peace be upon him) were known, that is indeed the case.
