A popular shopkeeper was stabbed to death by another Muslim in a "religiously prejudiced" attack hours after posting an Easter message on Facebook to "my beloved Christian nation".
Asad Shah, 40, a devout Muslim originally from the Pakistani city of Rabwah, had his head stamped on during a savage attack, according to one eyewitness.
Around four hours earlier the victim wrote online: "Good Friday and a very Happy Easter, especially to my beloved Christian nation.
"Lets follow the real footstep of beloved holy Jesus Christ and get the real success in both worlds."
On Friday afternoon, police confirmed that a 32-year-old Muslim man had been arrested in connection with Mr Shahs death.
A spokeswoman added: "A full investigation is under way to establish the full circumstances surrounding the death which is being treated as religiously prejudiced."
My heart goes out to the family of Asad Shah, a popular shopkeeper in my constituency. My thoughts are with them. https://twitter.com/bbcscotlandnews/status/713360000865943552 …
The victim was found seriously injured on Minard Road, Glasgow, and was taken to the Queen Elizabeth University Hospital where he later died on Thursday.
An eyewitness, who did not want to be named, told the Daily Record: “As I drove past I saw two men standing over the victim.
"One was stamping on his head. There was a pool of blood on the ground. It was horrific.
“The police arrived in minutes and the poor guy was getting CPR at the scene. I really hope he pulls through.”
On his Facebook page, Mr Shah describes himself as the self-employed owner of Shahs Health and Fitness. His social media account also features videos of Mr Shah in prayer.
In previous posts, he also called "unconditional real love for all mankind".
A police incident unit is stationed near the murder scene, while a body tent is visible.
Resident Isabella Graham, 64, said Mr Shah had previously employed her daughter at the shop. She said: "He was an amazing, wonderful man, he couldnt do enough for you. He wouldnt hurt anybody. Nobody in Shawlands would have a bad word to say about him. I cant believe hes gone."
Brothers Qaiser and Omar Khan told BBC Scotland they knew Mr Shah well and had repaired his cars in the past. They described him as "a humble, sweet person".
Omar Khan added: "Ive known him since I was a wee boy so this is shocking news. He was a very straight-forward, humble person who was very good with his customers. He cared about his family a lot."
Another local resident, Robert Maitland, said: "He was very friendly. Every morning we shook hands and said have a nice day. He was just a pleasant, lovely lad."
The vigil, advertised on social media, was to be held as close to the areas Waverley Gardens as the police cordon would allow. People attending were encouraged to bring a daffodil.
In a statement, Nisreen Sharif and Eildon Dyer, the organisers, said: "As a community we are coming together to mourn his death and as a small sign of sympathy towards his family."
A fundraising campaign on the GoFundMe website was set up on Friday after news of his death emerged, with the proceeds going to his family "to show how much he was cared for".
It had raised more than £5,000 within six hours of being set up.
