More than two million Muslims now live and work in Moscow. It has become one of the biggest cities for Muslims in Europe and its few houses of worship can no longer cope.
During Friday prayers the historic building is overflowing and thousands of faithful are praying outside in the snow.
Cars honk their horns and local people struggle to get past on the pavements.
It is a scene repeated at all of Moscow’s four mosques, as tens of thousands of Muslims gather for prayers every Friday.
