ユースフ・イスラムは、2001年9月11日のアメリカ同時多発テロに対して、即座に、そして激しくこう訴えた-
"I wish to express my heartfelt horror at the indiscriminate terrorist attacks committed against innocent people of the United States yesterday. While it is still not clear who carried out the attack, it must be stated that no right-thinking follower of Islam could possibly condone such an action. The Qur'an equates the murder of one innocent person with the murder of the whole of humanity.
