Sir Salman Rushdie’s plans to publish a book about a 2022 attempt on his life may delay the trial of his alleged attacker, which is scheduled to begin next week, lawyers said.

Hadi Matar, the man charged with repeatedly stabbing Sir Salman as the author was being introduced for a lecture, is entitled to the manuscript and related material as part of his trial preparation, Chautauqua County Judge David Foley said during a pre-trial conference.

Mr Foley gave Matar and his lawyer until Wednesday to decide if they want to delay the trial until they have the book in hand, either in advance from the publisher or once it has been released in April. Defence lawyer Nathaniel Barone said he favoured a delay but would consult with Matar.

Jury selection is scheduled to begin on January 8.

“It’s not just the book,” Mr Barone said. “Every little note Rushdie wrote down, I get, I’m entitled to. Every discussion, every recording, anything he did in regard to this book.”

Sir Salman, who was left blinded in his right eye and with a damaged left hand in the August 2022 attack, announced in October that he had written about the attack in a memoir: Knife: Meditations After an Attempted Murder, which is available for pre-order. Trial preparation was already well under way when the lawyers involved in the case learned about the book.

District Attorney Jason Schmidt said Sir Salman’s representatives had declined the prosecutor’s request for a copy of the manuscript, citing intellectual property rights. Mr Schmidt downplayed the relevance of the book at the upcoming trial, given that the attack was witnessed by a large, live audience and Sir Salman himself could testify.

“There were recordings of it,” Mr Schmidt said of the assault.

Matar, 26, of New Jersey has been held without bail since his arrest immediately after Sir Salman was stabbed in front of a stunned audience at the Chautauqua Institution, a summer arts and education retreat in western New York.

Mr Schmidt has said Matar was on a “mission to kill Mr Rushdie” when he rushed from the audience to the stage and stabbed him more than a dozen times until being subdued by onlookers.

A motive for the attack was not disclosed. Matar, in a prison interview with The New York Post after his arrest, praised late Iranian leader Ayatollah Ruhollah Khomeini and said Sir Salman “attacked Islam”.

Sir Salman, 76, spent years in hiding after Ayatollah Khomeini issued a 1989 edict, a fatwa, calling for his death after publication of his novel The Satanic Verses, which some Muslims consider blasphemous. Over the past two decades, Sir Salman has travelled freely.

Matar was born in the US but holds dual citizenship in Lebanon, where his parents were born. His mother has said that her son changed, becoming withdrawn and moody, after visiting his father in Lebanon in 2018.
