Is standing at 'Arafah on a Friday given any special virtue?

Question:
Regarding Hajj: In some Islamic countries, if standing at 'Arafah falls on a Friday, the scholars of those countries say: This Hajj is as if a person performed Hajj with the Prophet, as if it has a special virtue, so that the pilgrims from those countries increase in number. Is there any evidence for this?

Answer:
What do they do?
Q: The pilgrims come in large numbers, saying: This Friday has a special virtue over the other days for standing at 'Arafah?
A: Meaning: They gather in their mosques?
Q: No, they come to perform Hajj; because they say: This is better than the rest...?
A: No; because it is a merit that coincided with the Hajj of the Prophet (peace and blessings be upon him), otherwise the hadiths regarding it are weak. But its meaning is that it coincided with the Hajj of the Prophet (peace and blessings be upon him), so the Prophet performed Hajj on a Friday.
Q: Meaning: It has a special virtue?
A: Yes; because it contains an hour in which supplication is answered, after 'Asr.
