Isn't it a bit odd that none of our "celebrity" sports and entertainment business Muslims have much to say concerning their mosque visits. If anyone would know what's going on in there, they would certainly be aware of the atmosphere and the plans of the members at large, wouldn't they?
Not really. Plans are not literally made at the mosque during events. The violent interpretations from the Quran may be quoted; but plans are not normally discussed there.
The 'men' meet once a week at rotated locations. This is when plans are made if they are a cell.
