Whoever kills a soul, it is as if he has slain all humanity (5:32).
Respond with peace in the face of hostility (25:63).
Fight only those who fight you and do not commit aggression (2:190).
God commands you to treat with compassion and justice those who do not fight you (60:8).
Islam in the minds of Muslims
Whoever kills a soul, it is as if he has slain all humanity (Qur’an 5:32)
A person can only remain sound in his faith so long as he does not unlawfully shed blood.
Islam in the minds of terrorists
The sharīʿah is founded upon wisdom and the well-being of humanity in this life and the next. It is in its entirety justice, compassion, prosperity, and wisdom, and therefore anything which departs from justice to injustice, from compassion to its opposite, from welfare to harm, or from wisdom to nonsense, then it is not part of the sharīʿah, even if it’s included therein by misinterpretation.
Ward off the ḥudūd as much as you can; if there is any possible way to give the accused the benefit of the doubt, then do so. For a judge to err in pardon is far better than his erring in punishment.
The media and public representation of Islam
The pattern of militarism that began in the Persian Gulf in the 1970s has partly been the product of American support for and deliberate militarization of brutal and vulnerable authoritarian regimes. Massive weapons sales to oil autocrats and the decision to build a geopolitical military order in the Gulf that depended on and empowered those rulers resulted in a highly militarized and fragile balance of power.
Far from being religious zealots, a large number of those involved in terrorism do not practise their faith regularly. Many lack religious literacy and could actually be regarded as religious novices. Very few have been brought up in strongly religious households, and there is a higher than average proportion of converts. Some are involved in drug-taking, drinking alcohol, and visiting prostitutes. MI5 says there is evidence that a well-established religious identity actually protects against violent radicalisation.
The main reason [for focusing exclusively on ideology] is that these scholars have never lived with, and often never even spoken to, Muslims from different countries and communities.
The utopian ‘khilāfah’
Dehumanization in the name of walā’ wal-barā’
God does not dissuade you from dealing justly and compassionately with those who do not fight you on account of your faith nor drive you from your homes; indeed, God loves those who are just (Qur’an 60:8).
Do not say to those who offer you greetings of peace, ‘You are not a believer!’ (Qur’an 4:94).
Whoever accuses his brother of disbelief, then surely one of them is such.
Permission to fight is granted to those who are being fought because they have been oppressed, and verily God is capable of granting them victory; those who were driven from their homes for no reason other than professing their faith in God as their Lord. And had God not granted people the ability to defend themselves against others it would have resulted in the destruction of churches, synagogues, monasteries, and mosques. (Qur’an 22:39–40)
The one who performs jihad is the person who struggles against his own desires for the sake of God. 
If they desist, then let there be no aggression except against the oppressors. (Qur’an 2:193)
