Entering the mosque, taking his shoes off, he chatted with friends. He revealed plans for an October holiday back to Pakistan. Suhail hadn't been home in three years and he wanted to see his mother.
But at 1.40pm, a heavily-armed terrorist walked into the Deans Ave mosque and gunned him down, along with scores of others.
Asma soon heard there had been a shooting at the masjid. Suhail wasn't answering either his work phone or personal phone.
"I thought maybe Suhail will call me, maybe he's injured, I didn't know where he was. But he never called me," Asma said.
She phoned her older brother-in-law Naveed in Sydney. He started phoning police and St John for information on the wounded or missing.
He saw early media reports of nine people confirmed dead. He kept ringing. Suhail wouldn't answer.
That night, he spoke to one of Suhail's neighbours. He'd been shot in the neck but had been patched up and discharged from hospital. He had no news on Suhail.
Naveed, 40, jumped on a plane. He is a trained chemical engineer like his brother. He'd chosen Sydney for a better life, while another brother Tanveer, 38, had gone to the States, living in Connecticut.
Suhail had moved from Lahore to Auckland in 2017. He'd had a well-paid job at ICI Pakistan Limited (Imperial Chemical Industries), his own house and car and "everything you could dream of growing up in Pakistan", Naveed said.
But he wanted to give his family every opportunity he possibly could.
His work gave him time off every Friday to attend prayers. He'd make the time up by working later.
It took two days to confirm that Suhail had died.
On Saturday, he wasn't on a list of the injured. And on Sunday, an official was reading the names on a preliminary list of the dead. Suhail's name was halfway down page two.
"Then I knew my brother was no longer in this world," Naveed said.
They laid him to rest during the mass burial at Memorial Park Cemetery in Christchurch on Friday.
The Shahids still don't know exactly how Suhail died. They would like to know the exact details, they say.
"Everyone has been so supportive, including the Government. They can't bring our loved one back, but they have honoured us and given us respect. They are all mourning with us."
