Ali 'Imran 3:97

Feehi ayatun bayyinatunmaqamu ibraheema waman dakhalahu kana aminanwalillahi AAala annasi hijjualbayti mani istataAAa ilayhi sabeelan waman kafarafa-inna Allaha ghaniyyun AAani alAAalameen

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

In it there are clear signs: The Station of Ibrāhīm! Whoever enters it is secure. As a right of Allah, it is obligatory on the people to perform Hajj of the House - on everyone who has the ability to manage (his) way to it. If one disbelieves, then Allah is independant of all the worlds.
