The Pious Companions of the Prophet (pbuh): The Prophet (peace be upon him) had rightly guided successors among his blessed companions, who followed his footsteps (Sunnah) to the best of their abilities in spreading knowledge, preaching Islam, and managing the affairs of Islamic State. The disputes that took place among the Prophet’s Companions were the result of sincere interpretations that they worked hard to reach. Whoever was right among them will be rewarded twice, and whoever was wrong among them will be rewarded once and his mistake will be forgiven. It may not be appropriate for any believer to criticize them rather they deserve of beautiful praise. (Qur’an;7:42-43, 57:10, 9:100 & 59:10).
Peace is a state of harmony characterized by the lack of violence, conflict behaviors and the freedom from fear of violence. Commonly understood as the absence of hostility, peace also suggests the existence of healthy or newly healed interpersonal or international relationships, prosperity in matters of social or economic welfare, the establishment of equality, and a working political order that serves the true interests of all.
From the Latin pax, meaning "freedom from civil disorder," the English word came into use in various personal greetings from c.1300 as a translation of the Hebrew shalom. Such a translation is, however, imprecise, as shalom, which is also cognate with the Arabic "salaam", has multiple other meanings in addition to peace, including justice, good health, safety, well-being, prosperity, equity, security, good fortune, and friendliness. At a personal level, peaceful behaviors are kind, considerate, respectful, just, and tolerant of others' beliefs and behaviors — tending to manifest goodwill.
This latter understanding of peace can also pertain to an individual's introspective sense or concept of her/himself, as in being "at peace" in one's own mind, as found in European references from c.1200. The early English term is also used in the sense of "quiet", reflecting calm, serene, and meditative approaches to family or group relationships that avoid quarreling and seek tranquility — an absence of disturbance or agitation.
In many languages the word for peace is also used a greeting or a farewell, for example the Hawaiian word Aloha, as well as the Arabic word salaam. In English the word peace is occasionally used as a farewell, especially for the dead, as in the phrase Rest In Peace. Buddhists believe that peace can be attained once all suffering ends. They regard all suffering as stemming from cravings (in the extreme, greed), aversions (fears), or delusions. To eliminate such suffering and achieve personal peace, followers in the path of the Buddha adhere to a set of teachings called the Four Noble Truths — a central tenet in Buddhist philosophy.
Islam means submission. Muslim, etymologically directly related to salaam and the name Islam, means a person who submits to Allah in salaam. Submission to Allah is based on humility. An attitude of humility within one's own self cannot be accomplished without total rejection of violence, and a personal attitude and alignment toward peace.
Peace is a basic concept in Islamic thought. The Arabic word salaam (سلام) ("secured, pacified, submitted") has the same root as the word Islam. One Islamic interpretation is that individual personal peace is attained by utterly submitting to Allah. The greeting "As-Salaamu alaykum", favoured by Muslims, has the literal meaning "Peace be upon you".
The series of prophets and messengers coming from God throughout the ages to call the people again towards their innate identity of love and friendship.
The good life according to Islam is in submitting to God and in worshiping Him as The Creator and The Master and to recognize the innate nature of man. The individual who will recognize his true nature on which every person is created will be able to live together in society with peace and affection to each other.
In his Last Sermon, the Prophet Muhammad admonished believers: “Hurt no one so that no one may hurt you.”
