Germany has some four million adherents to Islam, but as David Wroe reports, a small group of Muslims is making a big effort to become a recognised part of German society.
When the Ahmadi Muslim community was building a mosque in eastern Berlin last year – the first in formerly communist East Germany – they didn't expect it to be easy. But nor did they expect death threats.
"I was standing on the road," said Abdul Basit Tariq, the mosque's Imam. A man stood there and stared at me with very sharp eyes and said, 'I will kill you.'"
