Quran 3:96 — The Amramites (Ali-'Imran)

The most important shrine established for the people is the one in Becca;* a blessed beacon for all the people.

[3:95] Say, "GOD has proclaimed the truth: You shall follow Abraham's religion—monotheism. He never was an idolater."

[3:97] In it are clear signs: the station of Abraham. Anyone who enters it shall be granted safe passage. The people owe it to GOD that they shall observe Hajj to this shrine, when they can afford it. As for those who disbelieve, GOD does not need anyone.
