Muslims must pray 5 times a day, so the prayers are evenly spread out through the day.  They want to build Europe's biggest mosque, holding 5000  people directly across the Thames from Parliament  in London.  The  amplified calls  to prayer on huge speakers would drown out any and all other talk, in and around  Parliament and Westminster Abby 5 times a day. It is not to join with English society but to bury it.
