Government policies, including those linked to security and extremism, are having a “negative impact” on British Muslims, a campaign body’s report says.
Some 56% said they had experienced verbal abuse, and 18% had faced physical assault.
The Home Office said it was committed to combating “anti-Muslim hatred”.
Of those questioned, 59% believed political policies had negatively impacted their lives. A smaller study by the organisation in 2010 recorded nearly a third of people as saying this.
In the latest survey, more than half (58%) said they had been treated with suspicion by society, while 93% said they had seen negative stereotypes of Muslims portrayed in the media.
The IHRC has been carrying out research into discrimination against Muslims for nearly two decades.
The report’s author, Arzu Merali, said: “We have an environment now, where Muslim people feel they are suspected and where life is increasingly difficult. The impact of government policies, in particular those related with security, have really had an impact on silencing Muslims – not from a point of view of just talking about political issues, but even to report anti-Muslim hatred.
According to the report, most Muslims from all backgrounds felt they had experienced some form of prejudice.
Some 40% believed they had faced discrimination at work, while 36% said they had experienced discrimination in education. Meanwhile, 56% said they had experienced verbal abuse, and 18% had faced physical assault.
Last month, the prime minister announced anti-Muslim hatred would be recorded by police forces in England and Wales as a specific hate crime for the first time.
This was welcomed by the IHRC, although Ms Merali said more needed to be done to tackle Islamophobia.
“What we really need is a cultural change, not just some laws here or there. Unfortunately, we have institutional problems that need to be addressed,” she said.
A Home Office spokesman said: “This government is committed to combating all forms of hate crime and has done more than any other to counter anti-Muslim hatred.”
He said policies such as Prevent were aimed at “protecting those who might be vulnerable to the poisonous and pernicious influence of radicalisation”. And the government was “continuing to work in partnership with communities of all faith backgrounds to challenge those who spread hatred and intolerance”.
