Sulayman Keeler (born Simon Keeler) is the leader of Ahlus Sunnah wal Jamaah, a British Islamist organization. He is a former member of Al-Muhajiroun, a banned organization designated as a terrorist organization, and led the Society of Converts to Islam.
The Sun newspaper report that he is believed to be the first white British Muslim to be convicted of an extremist offence.  and HSToday report that this is the "first time a white convert has been incarcerated for Islamist terror charges in the UK."'
A court sentenced Keeler to twenty-eight days imprisonment after he assaulted a police officer during a demonstration in London in December 1998. Years later he was again arrested after he assaulted British National Party (BNP) members at a rally.
In an interview with BBC News', Keeler expressed his opposition to democracy, and compared British Prime Minister Tony Blair to Al-Qaeda leader Osama bin Laden, saying, "I don't believe in democracy. It's man made. You're talking about a government that taxes the people to death. It oppresses many millions of people in the world. It wouldn't be such a shame to have them overturned... Tony Blair, sends a bunch of aircraft into Iraq, bombs a bunch of people... Osama Bin Laden, who sends a bunch of aeroplanes into America and bombs a bunch of people - what is the difference? You tell me."
On Thursday 17 April 2008, Keeler was one of 6 individuals found guilty of terror related offences, specifically terrorist fundraising. The others found guilty at Kingston Crown Court were Abu Izzadeen, Omar Zaheer, 28, of Southall, west London, Abdul Saleem, 32, of Poplar, east London, and Jalal Hussain. Two others, Ibrahim Abdullah Hussan, 25, from Leyton, east London, and Rajib Kahn, 29, from Luton in Bedfordshire, were released after the jury were unable to decide a verdict.
