How did Adam a.s perf0rmed Hajj?

BISMIL LAHI RAHMANIN RAHIM KA'ABA WAS NOT BUILD BY ADAM, BUT WAS ACTUALLY BUILD BY THE ANGELS AND IS DIRECTLY UNDER THE HOLY BAITUL MA'AMUN ABOVE. AND WHEN ALLAH (SWT) ASKED ADAM TO COME DOWN FROM JANNAH WITH HIS WIFE HAUWA, THEY EVENTUALLY MEET AT MOUNT ARAFAT AND KA'ABA WAS THERE UNTIL DURING NOAH (AS)WHEN THE DUFANA (FLOOD) DESTROYED THE HOLY KA'ABA. IT WAS DURING THE TIME OF ABRAHAM (AS) THAT ALLAH (SWT) DIRECTED HIM TO REBUILD THE KAABA WHILE THE ANGELS SHOWED HIM THE ACTUAL PLACE WHERE KA'ABA WAS. AND THAT IS HOW THEY REBUILD THE KA'ABA WITH HIS SON ISMA'IL (AS). THE MAKAMA IBRAHIM CURRENTLY IN THE KA'ABA WAS THE FOOTSTEP OF ABRAHAM WHERE HE STANDS WHILE HE WAS REBUILDING THE KA'ABA. ALLAH (SWT) KNOWS THE BEST. ASSALAMU ALAIKUM.**

There are various traditions (of questionable authenticity) which say that the first Ka'bah was built by the angels, and Adam found it by following them, or that the angels showed him the site and Adam built the first Ka'bah there, or that the Ka'bah was sent down with Adam when he was exiled to Earth. By similar traditions, the original building was destroyed and rebuilt over the ages (Noah, for example, rebuilt it after the Great Flood), until eventually Abraham and Ishmael were led to the site and built the current house on the original foundations.

Even now, the Ka'bah at Mecca is not the same one built by Abraham and Ishmael; it has been razed and rebuilt multiple times since the advent of Islam. The Hajj persists because the site itself is holy; the physical house itself is sacred because of the site, not vice-versa.

actually the place that the ka'ba is at has always been holy at we know the ka'ba wasent there when hajar was looking for zamzam water or when prophet abraham allehi salam left her there and yet she still went around the saffa and marwa many islamic scholers say based on some hadiths that adam used to go to the place of hajj even though there was no building there and do the hajj rituals as did the other prophet it wasent a random choice to build the ka'ba there the land has always been holy as was jeruslalem so there was no need of a ka'ba the land itself is holy

assalamoalaikom hajj was not an obilgatory act upon Adam as or any muslim before that great sacrifice intended by Abraham as it was only then that Allah swt ordained the act.
