Islam is the Faith of Peace
Islam means to submit to Allah, adhere to obeying Him, and be free from worshipping any others besides Allah. There is no good except that Islam ordered for it to be done, and there is no evil except that which it prohibited. Applying Islam guarantees everyone to be able to live in security and peace in light of its system, which safeguards rights for all.
Allah says: 
Say, ‘Come, I will recite what your Lord has prohibited to you. He commands that you not associate anything with Him, and to parents, good treatment, and do not kill your children out of poverty; We will provide for you and them. And do not approach immoralities - what is apparent of them and what is concealed. And do not kill the soul which Allah has forbidden to be killed except by legal right. This has He instructed you that you may use reason. And do not approach the orphan’s property except in a way that is best until he reaches maturity. And give full measure and weight in justice. We do not charge any soul except with that within its capacity. And when you speak be just, even if it concerns a near relative, and the Covenant of Allah fulfill. This has He instructed you that you may remember.’ 
(6:151-152)
Allah also said: Indeed, Allah orders justice and good conduct and giving to relatives and forbids immorality and bad conduct and oppression. He admonishes you that perhaps you will be reminded (16: 90)
Hence, the Faith of Islam is a comprehensive Faith of peace in all meanings of this word. This applies to the internal level of Muslim society as Allah said: And those who harm believing men and believing women for something other than what they have earned have certainly born upon themselves a slander and manifest sin (33: 58)
The Prophet Muhammad 
said:
“A Muslim is a person whose tongue and hand is safeguarded against, and an emigrant is a person who has left that which Allah prohibited” (Agreed upon)
He also said: “A believer is a person whom people trust...” (Tirmithi)
Islam also provides peace on an international level established through friendly relationships that are founded on security, stability and the foundations of Islam. Moreover, a Muslim society does not transgress against another society, especially those that are sincere in Faith, nor set up enmity against its adherents. According to the words of Allah:
O you who have believed, enter into Islam completely and perfectly and do not follow the footsteps of Shaytan. Indeed, he is to you a clear enemy (2: 208)
The Faith of Islam enjoins justice and forbids oppression, even with those who oppose these principles. Allah said:
O you who have believed, be persistent in standing firm for Allah, witnesses in Justice, and do not let the hatred of a people prevent you from being just. Be just; that is nearer to Righteousness and fear Allah. Indeed, Allah is Acquainted with what you do (5: 8)

As-Salaam (The Source of Peace, one of the beautiful names of Allah) has said:
He is Allah, other than whom there is no deity, the Sovereign, the Pure, the Perfection, the Bestower of Faith, the Overseer, the Exalted in Might, the Compeller, the Superior. Exalted is Allah above whatever they associate with Him. (59: 23) -
As-Salam, is also one of the names of Paradise. Allah the Most High said:
For them will be the Home of Peace with their Lord, and He will be their protecting Friend because of what they used to do. (6: 127) -
As-Salam is moreover the greeting of the Muslims to one another in this life, and the greeting of the people of Paradise in the Hereafter. Allah said:
Their greeting the Day they meet Him will be, ‘Peace,’ and He has prepared for them a noble Reward. (33: 44)
If you see a Muslim greet a fellow Muslim, you will hear them say, “As-Salaamu Alaykum”! It is a greeting as well as a supplication which brings tranquility, happiness and ease for the greeting and the greeted person. This is because of the expression of security and safety within this greeting. This, the Prophet established as one of the perfecting actions of a persons belief. He said: “You will not enter Jannah until you believe, and you will not believe until you love each other. Shall I not guide you towards a thing, that if you do it, you would love each other? Spread the greeting of peace among you!” (Muslim)
The Messenger of Allah taught us that this is one of the best actions. This is because the greeting brings hearts closer and softens them when it is given or heard. It also removes differences and hatred. When the Prophet was asked, “Which part of Islam is best?” He replied, “To feed people and give the greeting of peace to those you know and those you do not know!” (Bukhari and Muslim)
Hence, the Faith of Islam brought regulations and legislation that covers areas such as war, marriage, economics, politics, worship, etc. It was for an ideal, virtuous society to implement and regulate a Muslim’s relationship with their Lord, their community and the surrounding world – whether the human world or the animal and plant kingdom. The whole of humanity is unable to produce the like of Islam. A Faith of this perfection and comprehensiveness is deserving of being embraced, invited towards and respected.
