Over 90 mosques across Britain are opening their doors to visitors to allow Muslims to "explain their faith beyond the hostile headlines".
The Muslim Council of Britain hopes Sunday's open day will show unity in "a tense time for faith communities", BBC reported.
The Visit My Mosque Day comes after a rise in the number of anti-Muslim attacks in London, with hundreds reported last year.
There are about three million Muslims - about 5 percent of the population - and an estimated 1,750 mosques in the country.
The mosques involved in the open day include those in London, Birmingham, Manchester, Leeds, Glasgow, Cardiff and Belfast.
Organisers said the list represents the diversity in Islamic traditions, with mosques from a wide variety of Islamic schools of thought and traditions taking part.
They said mosques would be inviting leaders of other faiths, "and all will be asked to come together to demonstrate unity and solidarity during what has been a tense time for faith communities."
