When facing a question like this, you may find a group of people who try to justify that Islam is not a religion of peace. They usually refer to terrorist attacks by pseudo-Muslims and conclude that Islam is not a peaceful religion. Peace in Islam is a value and an ultimate goal of life; may it be personal, social or worldwide.
But let’s see what is Islam’s viewpoint about war and if it approves terrorism.
Before discussing the main topic of this article, we have to understand what peace in Islam means. According to Merriam Webster dictionary, “peace is a state of tranquility or quiet such as:
Freedom from Civil Disturbance
A state of security or order within a community provided for by law or custom.
Freedom from disquieting or oppressive thoughts or emotions
Harmony in personal relations.” 
Therefore, there are two types of peace defined above; social and individual. Islam not only talks about individual peace, but also all of its rules are based on logic to shape a peaceful society. In this article, we would focus on social aspects of peace in Islam, either within one country or on what goes on between different countries.
Allah emphasizes in the Quran that Prophet Muhammad (PBUH&HP) is a mercy towards all human beings: “We did not send you but as a mercy to all the nations” (21: 107). It can be understood from this verse that a worldwide mercy, peace, and tranquility is the goal of sending Prophet Muhammad (PBUH) with the religion of Islam.
Imam Ali (AS) in his letter to Malik al-Ashtar (his appointed commander in another country) wrote: “Develop in your heart the feeling of love for your people and let it be the source of kindliness and blessing to them. Do not behave with them like a barbarian, and do not appropriate to yourself that which belongs to them. Remember that the citizens of the state are of two categories. They are either your brethren in religion or your brethren in kind. They are subject to infirmities and liable to commit mistakes.” 
He specifically notes that we should be tolerant of people who have no bad deeds against Muslims and the religion of Islam.
In social relations The Quran defines Muslims as moderate people; “Muhammad, the Apostle of Allah, and those who are with him are hard against the faithless and merciful amongst themselves. “ (48:29)
By referring to the above verse and by going through its interpretations we find out that “Muslims should be harsh on infidels. Who are these infidels? Muslims should not be harsh on anyone who does not believe in Islam. They should behave kindly towards those who are not opposed to them, who do not plot against them, and who do not seek to wipe out their nations - even if they follow other faiths.” While at the same time “Muslims should be harsh on those who fight against Islam and their identity, nationality, country, independence, honor, dignity, traditions, culture, and values.”  Therefore, it is completely rational for Muslims to defend themselves while their values are being attacked, and it has no contradiction with their peaceful nature.
In recent years we have seen different terrorist groups such as Taliban, Al-Qaida or ISIS, who under the name of Islam, have committed terrorist attacks in different countries. They refer to verses of the Quran that are about the holy struggle (Jihad) and use those verses as a permission for their terrorist acts.
However, their interpretations of the verses of the holy struggle (Jihad) are not correct. The fact is that war is prohibited in Islam, and Muslims are not allowed to start a war against other countries for the sake of conquest or even for spreading the religion of Islam. Jihad is allowed for Muslims only if:
They are attacked by other countries, and their lives and properties are at risk.
If other Muslim territories are under attack by oppressive governments.
If other powers attack Muslim territories to annihilate Muslims or their religion.
“In the holy struggle (Jihad), violating or infringing on others' rights is not allowed. Killing other people under baseless pretexts is not part of the holy struggle (jihad). Neither is killing those who are not Muslims. Such acts are not allowed in the holy struggle (Jihad). Not all those who believe in religions other than Islam should be treated with harshness. Rather, only those who are opposed to Islam, your independence and territorial integrity, and Islamic culture, identity, and values should be treated with harshness. If carried out under these conditions, the holy struggle (Jihad) is considered as a divine order and will bring about glory to nations.” 
It is only under these conditions that Muslims are allowed to fight against the oppressors. And even when they are allowed to defend themselves and enter the war, they have to make sure to follow the rules of war. They are not allowed to kill the children or elderly of the infidels, or to poison the cities of the infidels. 
They have to tolerate the refugees, and if they betray them, they will face punishment . Also, they should observe the rights of the captives of war :
“Allah does not forbid you from dealing with kindness and justice with those [polytheists] who did not make war against you on account of religion and did not expel you from your homes. Indeed Allah loves the just. Allah forbids you only regarding those who made war against you on account of religion and expelled you from your homes and supported [the polytheists of Makkah] in your expulsion, that you make friends with them, and whoever makes friends with them—it is they who are the wrongdoers.” (60: 8-9)
In conclusion, Islam is a religion of peace for Muslim people and peaceful people. It is not a passive religion to sit and watch all the cruel things that are happening in the world and smile at it. Islam is the life map for those who wish to reach human perfection which is only achieved by obeying all of its rulings. No matter you call it Islam or something else, but every sane human being, by studying The Quran and searching about Islam, will understand that Islamic rules have been designed to make the society a safe place for human growth.
Islam has spread much more quickly than the other religions all over the world. The question is how this has happened? And it becomes more important when we consider the situation in which Prophet Muhammad (PBUH&HP) emerged.
He (PBUH&HP) invited people to Islam while he did not have any wealth or position and even when his family opposed him; except his wife, Lady Khadija (AS), and his cousin, Imam Ali (AS). Several factors were involved which we will discuss in a series of articles. Here, the focus is on how pleasant characteristics of Prophet Muhammad (PBUH&HP) helped Islam to become well known throughout the world.
In the Quran it is emphasized that the morals and attitude of Prophet Muhammad (PBUH) was one of the factors which attracted people to Islam: “had you been harsh and hard-hearted, they (people) would have surely scattered from around you” (3:159). This pleasant behavior of the Prophet (PBUH&HP) which made people inclined to him and Islam is known to be due to the God’s mercy over him (PBUH&HP) (3:159).
Prophet Muhammad (PBUH&HP) was forgiving towards those who had bothered him or even insulted him. It is narrated that once, a Jew accused Prophet (PBUHHP) of owing him some money and insisted on paying him back immediately. Prophet (PBUH&HP) told him gently that he had made a mistake, but the man repeated his claim and suddenly assaulted the Prophet (PBUH&HP). The companions of Prophet (PBUH&HP) came to interfere, but he (PBUH&HP) said: “I know how to deal with my friend.” He (PBUH&HP) behaved very nicely such that the man acknowledged that this behavior is only expected from a prophet and he declared his belief and embraced Islam right there.
However, he (PBUH&HP) was very serious about applying Islamic regulations or others’ rights. It is narrated that a woman from Quraysh [i] had stolen something; she confessed and had to be punished. Many people, including her family, interfered to change the Prophet’s mind and to stop her punishment. Prophet (PBUH) told people that they had meddled because she was from a famous family, but there is no exception to Islamic rules.
To provide an exemplary leader for others, to train people to act alike, to valorize his companions and to convince people to follow his instructions, Prophet (PBUH) used to take advice. Of course, in the end, he (PBUH&HP) was the one who decided and made firm decisions: “consult them on the matter. And when you have decided, then rely upon Allah” (3:159).
“Invite (mankind) to the Way of your Lord with wisdom and fair preaching, and argue with them in a way that is better” (16:125). Unlike what is advertised against Islam, Prophet Muhammad (PBUHHP) never forced people or threatened them to accept Islam.
On the contrary, following the advice of the Quran, he promoted Islam with kindness, fairness, and wisdom. Instead of humiliating and discriminating non-Muslims, or being harsh and fierce, he used rational argument and discussion which also improved their rationality and thinking power . This followed the fact that embracing Islam should be according to the personal perception and understanding and it cannot be based on the imitation .
