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 which 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.
((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 one upon whom be Allah's Blessing and Peace said:
He also said:
“A believer is a person whom people trust!”
Islam also provides peace on an international level and it is established on forming friendly relationships that are founded on security, stability and establishing the foundations of Islam. Moreover, it is when a Muslim society does not transgress against another society, especially those that do not play with the Faith nor set up enmity against its adherents. This is according to the Words,
((O you who have believed, enter into Islam completely and perfectly and do not follow the footsteps of Shayttaan. Indeed, he is to you a clear enemy.)) (2: 208)
The Faith of Islam enjoins Justice and non-oppression, even with those who set up enmity against them. Allah said:
((O you who have believed, be persistently 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 Peaceful, is one of the All Praised’s Names.
((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-Salaam is one of the names of Allah's Garden, jannah. Allah the All 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-Salaam is the greeting of the people of jannah. Allah said:
((Their greeting the Day they meet Him will be, ‘Peace,’ and He has prepared for them a noble Reward.)) (33: 44)
As-Salaam is also the greeting of Muslims among themselves, As-Salaamu ‘Alaykum! It is a greeting which adds tranquility, calmness 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 (may Allah's Blessing and Peace be upon him) established as one of the perfecting actions of a person’s 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, you would love each other? Spread the Salaam! greeting among you!” (Reported by Muslim)
The one upon whom be Allah's Blessing and Peace established that this was 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 ands hatred. When the Prophet (may Allah's Blessing and Peace be one upon him) was asked, ‘ Which part of Islam is best?,’ he replied, “To feed people and give the Salaam! greeting to those you know and those you do not know!” (Agreed upon)
Hence, the Faith of Islam brought regulations and Legislations at times of dealings, war, marriage, economy, politics, worship etc. It was for an ideal, virtuous society to implement and regulate a Muslim’s relationship with his/her Lord, society and surrounding world, whether the human world or environment. 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, care to be taken to spread it, and not to set up enmity against it.
“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)
