The Kaaba (The Sacred House) in the Quran in the Holy Quran

(125) And [mention] when We made the House a place of return for the people and [a place of] security. And take, [O believers], from the standing place of Abraham a place of prayer. And We charged Abraham and Ishmael, [saying], "Purify My House for those who perform Tawaf and those who are staying [there] for worship and those who bow and prostrate [in prayer]."

(96) Indeed, the first House [of worship] established for mankind was that at Makkah - blessed and a guidance for the worlds.

(97) In it are clear signs [such as] the standing place of Abraham. And whoever enters it shall be safe. And [due] to Allah from the people is a pilgrimage to the House - for whoever is able to find thereto a way. But whoever disbelieves - then indeed, Allah is free from need of the worlds.

(95) O you who have believed, do not kill game while you are in the state of ihram. And whoever of you kills it intentionally - the penalty is an equivalent from sacrificial animals to what he killed, as judged by two just men among you as an offering [to Allah] delivered to the Ka'bah, or an expiation: the feeding of needy people or the equivalent of that in fasting, that he may taste the consequence of his deed. Allah has pardoned what is past; but whoever returns [to violation], then Allah will take retribution from him. And Allah is Exalted in Might and Owner of Retribution.

(97) Allah has made the Ka'bah, the Sacred House, standing for the people and [has sanctified] the sacred months and the sacrificial animals and the garlands [by which they are identified]. That is so you may know that Allah knows what is in the heavens and what is in the earth and that Allah is Knowing of all things.

(26) And [mention, O Muhammad], when We designated for Abraham the site of the House, [saying], "Do not associate anything with Me and purify My House for those who perform Tawaf and those who stand [in prayer] and those who bow and prostrate.
