The British fighter tweeted a picture of him and two other men kneeling behind two copies of the Qoran inside a lavish looking Mosque in some rare downtime from training for his superfight with Wladimir Klitschko on April 29 at Wembley. It was accompanied with the caption: 'Besides luck, hard work and talent - prayer is a solid foundation. It was nice to join my brother as he led through afternoon prayer.'
Some of his followers said they would never watch him again, while a vile post from a man identifying as Terry Johnson called on the Prime Minister Theresa May to deport Joshua for his faith in a twisted tweet, saying: 'Get out of my country.' Dozens of fans leapt to the defence of the heavyweight, pointing out the much-loved Muhammad Ali was a practicing Muslim.
