Day of arafah in the Quran

[miracle114]

Salaam all
I've heard numerous things about the day of arafah.
2 years of expiation of sins if you fast, the day of resurrection, hajj not  Valid if the arafah ritual not complete, etc
Does the Quran say or prove any secondary claims??

Here is brother Joseph's article of what is mentioned in the Qur'an about Hajj ....
