The Day of Arafah
Arafah: the main day of Hajj. The Prophet (صلى الله عليه و سلم) said in one hadith: “Hajj IS Arafah.” [Sunan Abu Dawud, book 10, #1944] How true that is–if you go to Arafah, but miss everything else, your Hajj is sound; and if you do everything else, but miss Arafah, your Hajj is not valid.
How much more important can you get than that?
Arafah, the day when millions of poeple gather in one place at one time to praise and supplicate to Allah.
