Harwin Central Mall: (Houston,TX) The very first store that you come to when you walk from the lobby of the building into the shopping area had this sign posted on their door. The shop is run by Muslims.
The sign says, "We will be closed on Friday, September 11, 2009 to commemorate the martyrdom of Imam Ali"
Ali was one of those who flew the planes into the trade center. Hope this store didn't make it to 2011. I have been in this mall many times when I lived in Houston.
