Salam,
Are you refering to the old British Airways building or shed that was bought and converted to a Mosque at Heathrow?
Salam
I have met some of the brothers from there, maa sha Allaah, the west Londoners manners and brotherhood seems better than East's!!! I know one of the Imaam's of that masjid, who has helped me out a bit in the past and recently, may Allaah reward him for his efforts.
