Muhajirun (Arabic: المهاجرون‎ The Emigrants) is an Arabic term used to describe the early, initial Muslims who followed the Islamic prophet Muhammad on his Hijra (withdrawal from Mecca to Medina). The early Muslims from Medina are called the Ansar ("helpers").

Hassan Butt (Kashmiri: हस्सन भट (Devanagari), حسن بھٹ (Perso-Arabic)) (born 1980, Luton) is the British Pakistani former spokesman of the radical Islamic group al-Muhajiroun who now calls on Muslims to "renounce terror".

Butt has claimed that before renouncing terror he sent arms to the Taliban, organised training for 200 British Muslims to fight in Jihad, collected monies for terrorism, incited others to terrorism, encouraged attacks on political and military targets in the UK and associated with the 7/7 bombers.

On May 9, 2008, British anti-terror police arrested Butt for questioning just as he was about to board a flight to Lahore, Pakistan. He was released after twelve days while the police investigation continues.

Manchester Police subsequently released extracts from their interviews with Butt in which he stated that "I've never met Osama bin Laden. I've never met anyone from Al-Qaeda, or anyone who claimed to be from Al-Qaeda at all in my entire life", and that he had stabbed himself "as part of the whole scam."

Abu Dujana Simak bin Kharasha (died 632) was a sahaba and a skilled swordsman who is mentioned in Hadith narrations from the six major Hadith collections of Sunni Islam.

Abu Dujana is remembered as being one of Prophet Muhammad most skilled companions in the battlefield, highly excelling in melee combat. He frequently distinguishing himself in battle by wearing a red band on his head, and engaged in bravado before fighting by strutting in front of his adversaries. In the Battle of Uhud, Prophet Muhammad gave Abu Dujana his sword as the often cited hadith narration reads:

During the Battle of Uhud, Abu Dujana pierced into the enemy's lines, and even came within striking distance to the notorious Quraish leader, Hind bint Utbah who was encouraging others to mutilate the body of dead Muslims. According to various accounts, Abu Dujana spared her since he did not want to stain Muhammad's sword with the blood of a woman.

Abu Dujana, during the Battle of Uhud, received several wounds in his back after placing himself around Prophet Muhammad so as to act as a protection from arrows.
