More than 12,000 young people from all over the UK and Europe are expected to attend a ‘Peace for Humanity’ conference in London.

The event is being organised by Minhaj-ul-Quran International (MQI), an Islamic organisation working for peace and integration and will take place at Wembley Arena.

The conference will be opened by MQI’s founder, Dr Muhammad Tahir-ul-Qadri, a leading Islamic scholar and thinker.

He will use the conference to issue a "Declaration for Global Peace and Resistance against Extremism" which will call for end to terrorism and extremist violence. He will launch a drive to secure one million signatures to support the declaration.

The “Peace and Humanity” conference will host a full day of speeches, entertainment, multi-faith sessions and collective public action to spread messages of peace, harmony and cohesion throughout communities and across religions following the tenth anniversary of 9/11.

It will also include a collective peace prayer involving all main faiths 10 years after that called by the late Pope John Paul in Assisi.

Video messages of support will be shown from the Deputy Prime Minister, Rt Hon. Nick Clegg, the Secretary of State for Local Government and Communities, Rt Hon. Eric Pickles and the Leader of the Opposition, Rt Hon. Ed Miliband.

The Mayor of London Boris Johnson has also supported the conference. Ban Ki-moon has also sent a message of support.

The conference will also hear from Deputy Mayor of London Richard Barnes, Dean of Royal Air Force College Dr Joel Hayward, Sajjad Karim MEP, UK Muslim scholars Shaykh Abdal Hakim Murad (also known as Timothy Winter) and Vice-Chancellor of Al-Azhar University, Cairo,prominent young scholar Shaykh Hassan Mohi-ud-Din Qadri, Mrs Ghazala Hassan, Dr Musharaf Hussain.

A special session of collective peace prayer will be held in which religious leaders of Hindus, Sikhs, Buddhists, Jews, Christians and Muslims will perform prayer for global peace according to their respective religion.

Building on previous internationally recognised Minhaj-ul-Quran events, including the Fatwa on Terrorism and the Anti-Terrorism Camp, this event will bring together eminent faith leaders and communities, dispelling myths and enhancing unity in the name of peace.

In his Global Declaration for Peace, Dr Tahir-ul-Qadri will say: “We send a message of peace and fraternity to all of humanity’s innumerable states, nations, communities and individuals along with a call for respect, dignity, compassion, equality, solidarity and justice for, and between, all people".

“We address our call for peace, tolerance and respect to all people everywhere, but especially to political and religious leaders and decision-makers as well as to scholars, teachers and journalists".

“We reject unequivocally all terrorism because at the heart of all religions is a belief in the sanctity of the lives of the innocent.

The indiscriminate nature of terrorism, which has in recent years killed far more civilians and other non-combatants than it has combatants.”
