One critic wrote: 'You are being given the name of our beloved prophet Mohamed and it is better to protect the honourable name and your religion of Islam.'
Another said: 'The respect I had for you went way down. Shame bro.' A third condemned the runner: 'Are you serious? You are Muslim you cant do this , I’m sorry for you.'
