Touching Sermon After Nationwide Call To Prayer

Thousands of New Zealanders have come together for a call to prayer and two minutes of silence, one week on from the Christchurch terror attack.

Friday's service was held in Hagley Park, Christchurch across from Al Noor Masjid, one of the mosques targetted in the terror attack that killed 50 people.

The Muslim Call to Prayer took place at  1:30pm local time -- 11.30am AEST -- and was broadcast across the country on television and radio.  A nation-wide two minutes of silence followed immediately after.

In Islamic tradition, Muslims are called to prayer five times a day by formal announcement called the adhan -- the Arabic word for "to listen".

The call to prayer is read in Arabic. A translation of the Sunni call to prayer is below:

God is the greatest 

I acknowledge there are no other gods but the One God 

I acknowledge that Muhammad is the messenger of God 

Come to prayer

Come to salvation 

God is the greatest 

There are no other gods but the One God

Following the call and two-minute silence, Imam Gamal Fouda addressed the crowd.

"Brothers and sisters in New Zealand," he began.

"Last Friday I stood in this mosque and saw hatred and rage in the eyes of the terrorist who killed and murdered 50 innocent people, wounded 42 and broke the hearts of millions around the world.

"Today, from the same place I look out and I see the love and compassion in the eyes of thousands of fellow New Zealanders and human beings from across the globe that fill the hearts of millions more who are not with us physically but in spirit.

"This terrorist sought to tear our nation apart with an evil ideology that has torn the world apart. But instead, we have shown that New Zealand is unbreakable."

The Imam was thankful to all those who had gathered, from all faiths, to show support and solidarity with the Muslim community.

New Zealand Prime Minister Jacinda Ardern -- who on Thursday announced a nation-wide ban on all military-style semi-automatic weapons -- was in attendance along with community leaders and foreign dignitaries.

Fouda addressed Adern specifically, thanking her for compassion and leadership in the wake of the attack.

"Thank you for your leadership," he said.

"It has been a lesson for the world's leaders. Thank you for holding our families close and honouring us with a simple scarf. Thank you for your words and tears of compassion. Thank you. For being one with us."

Former boxer and rugby league player Anthony Mundine was also among the crowd.

In Auckland, the city's four mosques opened their doors to all who wished to attend. A human chain was expected to form around a mosque in Ponsonby as a sign of protection.

All trains, ferry services, and buses stopped where possible in Auckland to observe the two-minute silence, Auckland Transport said.

A father and son, who arrived in New Zealand months ago after fleeing war-torn Syria, were the first victims of the Christchurch terror attack to be buried on Wednesday.

Among the hundreds of mourners who attended the service was Zaid Mustafa -- Khaled's son, Hamza's brother -- who was also injured in the attack.
