Mr Shah, 40, died following an incident at the newsagent’s shop he owned in Shawlands, Glasgow, last week.
His death has prompted an outpouring of grief throughout the community.
Customers and neighbours flooded social media with tributes to “the nicest guy on the planet” and a “pillar of the community”.
Last night Mr Shah’s father Syedna Shah, 75, said: “He was a brilliant man and we are grateful for the community support.”
Syedna had earlier said the family raced to the hospital but Mr Shah was dead before they arrived.
Mr Shah was allegedly stabbed to death hours after wishing people a happy Easter. He posted a message on his Facebook profile just four hours before his death saying: “Good Friday and a very happy Easter, especially to my beloved Christian nation.”
Police Scotland has confirmed the murder is being treated as religiously motivated.
A GoFundMe page to raise funds for the shopkeeper’s family had last night raised more than £30,000, with more than 2,000 people donating.
Jen Bannerman, who started the page, said Mr Shah was more than a shopkeeper, he was also a friend who had touched hundreds of lives and she wanted to give people a way to express their fondness for him.
“It is less about the money and more about showing support.
“The outpouring of support shows what a wonderful person he was,” she said.
More than 500 people, including First Minister and local MP Nicola Sturgeon, attended a vigil for the shopkeeper near the newsagent on Friday night.
A second act of remembrance took place at the shop yesterday.
Police have arrested a 32-year-old man. He is due to appear at Glasgow Sheriff Court on Tuesday.
