And finally, hopefully, acceptance. Sheikh Gamal Fouda, the imam of Al Noor mosque, traveled the world offering a message of peace. But he found his own inner peace here at home.

It wasn't until November that Sheikh Gamal Fouda really came to terms with what happened to his small community.

The imam of Al Noor Mosque spent the weeks and months after the attack travelling around the country and the world, at the invitation of governments, kings and religious institutions wanting to give a platform for the victims of Christchurch.

He was speaking at the United Nations, at Islamophobia forums in the US, at the royal court of Saudi Arabia. What he wasn't doing was dealing with his own trauma.

"I put these people in the same basket as Al Qaeda and ISIS and the Taliban, because terrorists are terrorists, whether they're using Islam or using Christianity or anything else. But I think religions must be part of the solution, not part of the problem."

Just one week later, he stood defiantly on a podium in the middle of Hagley Park, across the road from his cordoned mosque where forensic examinations were still underway, and gave a sermon to the world.
