CHRISTCHURCH (AP) - The scars from the nine bullets the gunman fired into Temel Atacocugu run down his left side like knotty rope. But it is the recurring mental images from that day at the mosque that he often finds hardest to cope with: The gunman's face. The puff of smoke from his gun. The worshippers falling as they clamoured to escape.

After coming so close to dying nearly five months ago, Mr Atacocugu feels he has been "reborn". And this week, he plans to express his gratitude to God for being given the chance for a new life when he participates in the haj, the holy Muslim pilgrimage to Mecca.

The 44-year-old kebab shop co-owner is among 200 survivors and victims' relatives from the Christchurch mosque shootings who are travelling to Saudi Arabia as guests of King Salman. The king is paying for their airfare, accommodation and travel costs, a bill that will run well over US$1 million (S$1.38 million). The group will also travel to holy sites in Medina.

All able-bodied Muslims are required to perform the haj once in their lifetime, with many saving for years to make the journey. The annual pilgrimage draws nearly two million Muslims from around the world to Mecca and sites around it to perform a series of ancient rites and prayers meant to cleanse the soul of past sins and bring people closer to God.

The Saudi ambassador to New Zealand, Abdulrahman Al Suhaibani, says King Salman was shocked by the March 15 attacks at two mosques in which an Australian white supremacist has been charged with killing 51 people.

The Christchurch shootings have been cited as inspiration by other white supremacists, most recently in an attack at a Walmart store in El Paso, Texas, that left at least 22 people dead.

Each year, the king invites several hundred people to perform the haj as his own guests, often selecting those most touched by tragedy that year. Mr Al Suhaibani said this is the first time the king has invited anyone from New Zealand on his annual programme to help get people to the haj who otherwise may struggle to make it.

Two weeks ago, the ambassador travelled to Christchurch to hand out the simple white garments the male pilgrims will wear. The terry cloth garments worn by men are meant to strip pilgrims of adornment and symbolise equality of mankind before God.

"It's a wonderful time and this is a golden chance for people to get spiritual elevation," says Mr Gamal Fouda, the imam at the Al Noor mosque, one of the two mosques that were attacked.

Mr Fouda, who also survived the shootings, is travelling with the group as a spiritual leader. He says that while all Muslims want to do the haj, many tend to delay their trips due to the expense, especially from distant New Zealand.

He says the memories of the shooting remain fresh in everybody's minds and his mosque hasn't yet returned to normal.

"The most important thing is that the New Zealand community, including Muslims, they stood together against hate," Mr Fouda says. "And we are still saying that hate is not going to divide us. We will continue to love each other."

Mr Atacocugu said he was feeling good on March 15 when he entered the Al Noor mosque for Friday prayers after finishing a final session with an acupuncturist, who was treating him for a sports injury.

When he saw the gunman walk into the mosque, he thought at first that he was a police officer because of his paramilitary clothing. Then the man started shooting and Mr Atacocugu found himself looking right at him as he fired a bullet into Mr Atacocugu's mouth, shattering his jaw.

"And then I said, 'Oh my God, I am dying.' When I see he's shooting, when I see the smoke, I said, 'Yeah, I'm dying.' That's the first thought," he said.

After falling to the floor, his left arm ended up protecting his vital organs as the gunman continued firing bullets into him.

Recovering at the Christchurch Hospital after the shooting, Mr Atacocugu could not eat for a week and could not walk for three weeks. But after several operations, he is now able to walk unassisted and get some use from his left hand. He has more surgery ahead and is being helped in Saudi Arabia by his 21-year-old nephew, who is travelling with him.

Another of those travelling to the haj is 33-year-old Aya Al-Umari, whose brother Hussein, 35, was among those killed at the Al Noor mosque.

"We had a very typical sibling relationship," she says. "So you have your nagging elder brother, nagging little sister. But at the end of the day, you love each other, even though you don't verbally say it. But you just telepathically know that."

She says witnesses and video taken by the gunman indicate her brother stood up to the attacker, allowing others to escape.

"So he fought to the very last minute," she says. "And this is Hussein, in his nature. He's always the type of person who would want to see if there is danger, he'd face it, he wouldn't escape from it."

When visiting Mecca, Ms Al-Umari says, she will pray for her parents and herself to have the patience to cope with the loss of Hussein. She also plans to pray for the other families from her mosque who lost loved ones. And she says she feels her brother will be with her in Saudi Arabia.

"I will carry his presence with me the whole time when I'm in Mecca," she says. "He is with us every day. But in the journey, I will feel like he will accompany me."

Ms Al-Umari says she wants to return to the haj another year.

"I will do my level best to make sure I fulfil my duty first, and then I will do it on his behalf next time," she says.

The haj is one of the five pillars of Islam. During the five-day pilgrimage, Muslims circle Islam's most sacred site, the cube-shaped Kaaba, and take part in rituals intended to bring about greater humility and unity.

Mr Fouda, the imam, says that while he has been to Mecca before, he has never been there during the haj, so it will be a special journey for him as well.

"I will pray for God to forgive my sins, because every human is sinful," he says.

"And I will also pray for the peace of the world. Peace for the people of Christchurch. Peace for the people of New Zealand. And peace for the whole world," he says. "We ask God that we find a better world than we live in, rather than spreading hate."
