A man who knew some of the 7 July bombers has been jailed for possessing an al-Qaeda training manual.
Mr Khaliq was arrested in Beeston, Leeds
Khalid Khaliq, 34, of Beeston, Leeds, admitted owning a CD containing the manual, which was found in a raid at his home in July 2005.
He went whitewater rafting with two of the bombers - Mohammad Sidique Khan and Shehzad Tanweer - one month before the attacks on London.
Khaliq was sentenced at Leeds Crown Court to 16 months in prison.
The court heard Khaliq, Khan and Tanweer were close friends and trustees of the Iqra Islamic book shop in Beeston, which was one focus of police operations following the London bombings.
Fifty-two people were killed and more than 750 injured when suicide bombers attacked three London Underground trains and a bus in July 2005.
Judge James Stewart QC said of the suicide bombers Khan and Tanweer: "They, among others, were responsible for the deaths of 52 innocent London folk going about their daily business."
On Monday, Khaliq admitted one count of possessing a document or record containing information likely to be useful to a person committing or preparing an act of terrorism.
A further count of possession of information likely to be used for terrorism was laid on file, and the judge ordered Khaliq should be cleared of a third similar charge.
The unemployed single father of three was one of four people arrested in West Yorkshire and Birmingham by anti-terror police officers on 9 May 2007.
The other three - Hasina Patel, the widow of 7 July ringleader Mohammad Sidique Khan, her brother Arshad Patel and Imran Motala - were released without charge a week later.
Prosecutor David Farrell QC told the court the al-Qaeda training manual included a declaration of Jihad, an interview with Osama bin Laden and information about weapons and how to deal with being interviewed by police.
