Recently there has been an international conspiracy against Islam and its Holy Founder the Holy Prophet Muhammad (may peace and blessings of Allah be upon him). To use vulgar language, obscene descriptions, distortion of the teachings of Islam and the noble character of the Holy Prophet Muhammad, negative propaganda, blasphemous criticism of the most Noble of the Prophets, and Islam - all this is done in the name of free speech and western civilized values.The Imam and the Supreme Head of the worldwide Ahmadiyya Muslim Community His Holiness Mirza Masroor Ahmad, Khalifatul Masih V delivered his Friday Sermon on September 21, 2012 at Baitul-Futuh Mosque in Morden, Surrey UK in response to the film "Innocence of Muslims" and the publication of cartoons in France depicting the Holy Prophet Muhammad (may peace and blessings of Allah be upon him). In this Sermon His Holiness set out what our response as Ahmadi Muslims must be. In this booklet we are presenting the English translation of this Sermon for the guidance of every one.
