He's an Amadiyyah Muslim. Amidiyyah Muslims are the guys who sell poppies.
Ahmadiyyah Muslims are pretty blooming amazing, they teach peace and tolerance, reaching out to all other faiths and include some aspects of other religions in their worship including viewing Jesus as a figure of great significance. Some interesting reading here:
www.alislam.org/introduction/
We have a lot of Amadiyyah where I live and they do an awful lot of outreach to the wider community including charity work and becoming socially active within the wider community. They do an awful lot of good for Muslim and non-Muslim alike and have a genuine message of peace and tolerance for all.
Unfortunately they are viewed as heretics and blasphemers and horribly, horribly persecuted in much of the Islamic world, especially in Pakistan where that persecution is state sponsored and includes things like denial of passports and public services right up to violence and murder.
I assume that him being Amadiyyah is a large part of the reason. Not a massive surprise this sort of thing is happening sadly.
