Joan Bakewell explores areas of belief with artists, thinkers and other public figures. She talks to Cambridge University chaplain and Muslim convert Tim Winter, known as Shaykh Abdal Hakim Murad. He explores the moral sense of the sacred, instilled in him by his mother, his search for a connection with his creator and what it means to be a Muslim convert in Britain today. Winter made his own journey towards Islam via the Unitarian church, bringing Western academic methods to his studies of Islam and its history. He is strongly critical of Wahhabism and of the kinds of Islamic interpretation and fundamentalism which underlie extremism and justifications of violence. A participant in inter-faith dialogue at high levels, he has recently returned from the Vatican in an attempt to improve Muslim Catholic relations.
