Asad Shah believed to have received death threats months before he died

But the 40-year-old didn't tell police or others in the Muslim community because he couldn't believe anyone would want to harm him.

The details emerged at a press conference held in the Ahmadiyya mosque in Yorkhill yesterday, where leaders condemned the attack on Mr Shah and called for unity against extremism.

Ahmed Owusu-Konadu, external affairs secretary for the Ahmadiyya Muslim Community Scotland mosque, said: "He had received some death threats on Facebook and Youtube but, unfortunately, we were not aware of them before he was killed.

"I only found out about them after a few colleagues looked around at his Facebook.

"No one I have spoken to was aware of the threats he had received before he was killed.

"If he had made the mosque aware of them then we would have passed that information on to the police.

"I doubt he would have anticipated that someone would go through with what they were saying."

"Death threats should be brought to the attention of the community and the police straight away so that steps can be taken to protect such people."

Asad Shah died in hospital on Thursday March 24, after a street attack near his newsagent shop in Shawlands.

In a statement, the Shah family said they were "devastated" by the death of "a brilliant man".

They said: "A beloved husband, son, brother and everyone’s friend, Asad Shah, was taken away from us by an incomprehensible act.

"We are devastated by this loss.

"A person’s religion, ethnicity, race, gender or socioeconomic background never mattered to Asad.

"He met everyone with the utmost kindness and respect because those are just some of the many common threads that exist across every faith in our world.

"He was a brilliant man, recognising that the differences between people are vastly outweighed by our similarities.

"And he didn’t just talk about this, he lived it each and every day, in his beloved community of Shawlands and his country of Scotland."

They said one of their "brightest lights" had been extinguished, and added: "Asad left us a tremendous gift and we must continue to honour that gift by loving and taking care of one another."

Mr Shah's brother also posted his own tribute on Facebook yesterday, describing him as "a hero, martyr and saint."

He also said he was "humbled' by the messages of support he had received and urged people to "be like Asad Shah and build peace and harmony."

Yesterday leaders of the Ahmadiyya Muslim community, of which Mr Shah was a member, condemned the attack in a joint statement with Interfaith Scotland.

They said they were "deeply saddened and shocked" by his death, and added: "The Islamic faith teaches us that killing one innocent person is akin to killing the whole of humanity."

However, the event was surrounded in confusion after members of other mosques across the city failed to attend, or sign the statement, which organisers had hoped they would.

The Muslim Council for Britain previously issued their own comments condemning the attack.

President of the Ahmadiyya community in Scotland, Abdul Abid, told of how other members of the community were left worried following Mr Shah's death.

He said: "Members of the community, some of them are worried as well.

"The police investigation is still on. We still don't know why Mr Shah was killed.

"We are in touch with [the family] and we are providing them food every day. Members of the community are visiting them too.

"It is very difficult for the family and that's why they are keeping a low profile."

More than £105,000 has now been raised online for Mr Shah's family, with more than 5000 people from across the globe donating money on fundraising site GoFundMe.
