Daqqa wrote several books during his imprisonment, several of which have been described as being
prison literature, and on politics and philosophy, and also a children's story. His works include
The Tale of the Secrets of Oil,
Fusion of Consciousness and
A Parallel Time. The latter book, together with material from a long letter he had written to former MK
Azmi Bishara,
The Tale of the Secrets of Oil narrates the story of a 12-year-old boy named Jude, who was conceived with his imprisoned father's sperm. It begins as the boy prepares to meet his father for the first time in prison, but Jude receives news that, "due to security reasons," his visit had been cancelled. Jude, who is heartbroken, goes for a walk in the countryside, engaging in a conversation with different species, including a rabbit, a cat, and eventually
an olive tree named Um Rumi, who is 1,500-year-old. They all listen to the boy's frustration over his canceled prison visit, and tell him of their suffering under the occupation and their struggle for freedom. Um Rumi, the olive tree, tells the boy of her experience when Israel had threatened to uproot her so that she could be moved from the West Bank to the Israeli city of
Afula. Afterwards, she tells the boy about her sacred oil, which she had been keeping as a secret. Jude rubs the oil on his skin, making him invisible, which helps him visit his father in prison. Upon hearing a child's voice say, "I am your son, Jude," his father thinks that he is losing his mind. The oil mentioned in the novel is made in reference to
Jesus, whose oil was claimed to be able to heal people's wounds. At the end of the book, Daqqa compares the literal prison to "a [metaphorical] larger one where Palestinians in the territories live under siege." Daqqa mentions in the prelude of the novel that he is writing: "until I am freed from prison, with the hope of freeing the prison from me." The explained goal of his novel is followed by the dedication: "To Jude, that he may live his childhood, to all the children who have become adults before their time and to all the adults who have been deprived of a taste of childhood by prison." ==Death==
