So far as Islam is concerned, it is an entirely tolerant religion. Islam desires peace to prevail in the world. The Qur’an calls the way of Islam ‘the paths of Peace’ (5:16). The state of peace can never prevail in a society if a tolerant attitude is lacking in the people. Tolerance is the only basis for peace; in a society where tolerance is absent, peace likewise will be non-existent.
Peace is the religion of the universe. Peace should, therefore, be the religion of man too, so that, in the words of Bible, the will of the Lord may be done on earth as it is in heaven (Matthew 6:10).
In a similar vein, the Qur’an tells us that: "The sun is not allowed to overtake the moon, nor does the night outpace the day. Each in its own orbit runs" (36:40).
When God created heaven and the earth, He so ordered things that each part might perform its function peacefully without clashing with any other part. For billions of years, therefore, the entire universe has been fulfilling its function in total harmony with His divine plan.The universe is following this path of peace—which is known in science as the law of nature as it is imposed upon it by God, whereas man has to adopt this path of peace of his own free will. This has been expressed in the Qur’an in these words: "Are they seeking a religion other than God’s, when every soul in heaven and earth has submitted to Him, willingly or by compulsion? To Him they shall all return" (3:83).
Peace is no external factor to be artificially imposed upon man. Peace is inherent in nature itself. The system of nature set up by God already rests on the basis of peace. If this system is not disrupted, it will continue to stay the course set for it by the Almighty. But the only way to keep humanity on the path of peace is to rid it of corruption. That is why the Qur’an enjoins: "And do not corrupt the land after it has been set in order" (7:85).
In order to preserve the peace, established by nature, from disruption, two important injunctions have been laid down by Islam. One, at the individual level, stresses the exercise of patience, and the other, at the social level, forbids taking the offensive.
Negative reaction on the part of the individual is the greatest factor responsible for disrupting peace in daily life. It repeatedly happens that in social life one experiences bitterness on account of others. On such occasions, if one reacts negatively, the matter will escalate to the point of a head-on collision. That is why Islam repeatedly enjoins us to tread the path of patience. The Qur’an says: Surely the patient will be paid their wages in full without measure (39:10).The reason for the rewards for patience being so great is that patience is the key factor in maintaining the desired system of God. In the words of the Qur’an the patient man is the helper of God (61:14).
The other injunction, designed to maintain peace in human society, forbids the waging of an offensive war. No one in Islam enjoys the right to wage war against another. There are no grounds on which this could be considered justifiable.There is only one kind of war permitted in Islam and that is a defensive war. If a nation, by deviating from the principles of nature, wages war against another nation, defense in such circumstances, subject to certain conditions, is temporarily allowed.
To sum up, Islam is a religion of peace. The Arabic root of Islam, ‘silm’, means peace. The Qur’an says: ‘...and God calls to the home of peace’ (10:25).
Peace is basic to all religions. Let us all strive then to establish peace in the world, for that is the bedrock on which all human progress rests.
