Sheikh Yousef Al-Qaradhawi, spiritual leader of the Muslim Brotherhood movement and the head of the European Council for Fatwa and Research, told www.islamonline.net [9] that he condemned the bombings in London: "We were dumbfounded by the grave news which surprised us, and all the world today, about the bombings that took place in the city of London, that killed dozens and wounded hundreds of innocent people who attacked no one and had committed no crime to remove the immunity of their blood."
Al-Qaradhawi described the bombings as "cruel and barbaric black actions that Islam harshly condemns." He also said, "[Even] In an official war, when state armies battle face to face, Islam does not permit the killing of women, children, elders, priests, farmers and merchants, and those like them, who are non-combatants, and whom nowadays we call civilians."
Al-Qaradhawi offered his condolences to the families of the victims, and sent a special letter of condolence to the mayor of London, which stated: "We express our condolences to our dear friend, London Mayor Ken Livingstone, a man of justice who always defends Arab and Muslim causes."

And concerning other types of attacks against civilians, he says:

TRANSLATION: 
It's not suicide, it is martyrdom in the  name of God, Islamic theologians and  jurisprudents have debated this issue.  Referring to it as a form of jihad, under  the title of jeopardising the life of the  mujahideen. It is allowed to jeopardise  your soul and cross the path of the  enemy and be killed.  
MARSHALL:
In the mind of Sheikh Yusuf Al- Qaradawi, that view prevails even  though women and children are often the  innocent victims.

TRANSLATION: 
Israeli women are not like women in our  society because Israeli women are  militarised. Secondly, I consider this  type of martyrdom operation as  indication of justice of Allah almighty.  Allah is just. Through his infinite  wisdom he has given the weak what the  strong do not possess and that is the  ability to turn their bodies into bombs  like the Palestinians do.
