Christians are meeting members of the Muslim community on Friday to pass on greetings for the feast of Eid.
Eid marks the end of Ramadan, a month-long period of fasting for Muslims.
The greeting has been undersigned by numerous churches, including the Church of England, the Baptist Union of Great Britain, the Catholic Church in England and Wales, The Salvation Army, and the Methodist Church.
They extend their greetings of "peace and prayers for God's blessing" on Muslims and assure them of their solidarity following recent attacks on mosques in the wake of the killing of Drummer Lee Rigby.
Church representatives will meet members of the Muslim community at the East London Mosque to pass the greeting on.
It reads: "As representatives of the main Christian traditions in the UK we assure you of our goodwill towards you, and our commitment to peace and justice in the society that we share together. Aware of the recent attacks on mosques and Muslims, we want to stand with you against any discrimination or violence targeting any community or person because of their faith.
"Instead, we want to work for more positive interaction between Christians and Muslims, demonstrating the love for God and neighbour to which we are called."
The greeting is supported by the Christian Muslim Forum and has been facilitated by Churches Together in Britain & Ireland and Churches Together in England.
