It is true that jihad is one of the most important teachings of Islam. But jihad is not synonymous with war. In Islam another word is used for war and fighting. This word is ‘qital.’ When the Qur’an refers to war or fighting, it uses the word qital and not jihad.
Jihad literally means to strive or to struggle. So jihad actually means peaceful struggle, especially for da‘wah work. The Qur’an says:
Do great jihad with the help of the Qur’an. (25:52)
The Qur’an is simply a book, and not a sword, so “do great jihad with the Qur’an” means do great jihad with the ideological power of the Qur’an. In fact, jihad is only another name for peaceful activism. And peaceful activism is the only weapon by which Islam wants to achieve all its aims and objectives.
The Qur’an has this to say of the mission of the Prophet Muhammad:
We have not sent you forth but as a mercy to mankind. (21:107)
In the Qur’an and the Hadith, there are many such references that go to prove that Islam is a religion of peace, love and human brotherhood. However, it is also a fact that in later times the image of Islam has altered drastically. Now Islam has come to be regarded as a religion of violence rather than as a religion of peace. It is not the media that has produced this transformation in the image of Islam. The responsibility for this falls on latter-day Muslims, who have failed to maintain the original image of Islam.
In actual fact, the mission of all the prophets, right from Adam to Christ (may peace be upon them all), was one and the same—of establishing the ideology of monotheism in the world, so that man might worship one God alone. As we know, there came a large number of prophets in ancient times, but the message of monotheism remained at the initial stage; it could not culminate in a revolution. This state continued up till the time of Christ, the last but one Prophet. The reason being that in ancient times, the system of monarchy was entrenched throughout the world. The kings, in order to secure their political interests, adopted the course of religious persecution. These kings suppressed all religious movements, which were different from the state religion. They would nip all apostasy in the bud, since they saw religion as a matter of affirming one’s loyalty to the state. If a person adhered to a religion other than the state religion, he was regarded as a rebel.
That is why in ancient times prophetic movements could go no further ahead than the stage of da‘wah. No sooner would a movement based on monotheism arise than the coercive political system would be activated to pull it out by its roots. The reason for the absence of any historical record of prophets (besides the Prophet Muhammad (may peace be upon him) in antiquity is traceable to the intense opposition of these coercive political systems. All the Prophets of ancient times, historically speaking, were like mythical beings, rather than real human beings accepted as historical figures. The Prophet Jesus was the last link in the chain of these persecutions faced by the preachers of monotheism. Then God decreed the abolition of this coercive political system, even if it entailed the use of force in order that the age of religious persecution might be brought to an end forever, and replaced by the age of religious freedom. This divine plan was brought to completion through the Prophet Muhammad (may peace be upon him) and his companions. This is the command given in the Qur’an:
“Fight them until there be no persecution and religion be wholly God.” (8:39)
Therefore the Prophet Muhammad received special divine succour in the form of a powerful team consisting of more than one hundred thousand individuals. Equipped with this team the Prophet waged war to end this coercive system of religious persecution, and it was in Arabia that it was first of all overthrown. Then within a very short span of time, they advanced to abolish the coercive system established by the Sassanid and Byzantine empires. In the wake of this Islamic action, the coercive system was abolished forever in the major part of the inhabited world of the time. This war waged by the Prophet Muhammad (may peace be upon him) and his companions was not a war as is commonly understood, but rather a divine operation, which was carried out by a people who possessed a high standard of moral character.
However, this operation was certainly only temporary in nature. Its goal was to put an end to the age of religious persecution and usher in the age of religious freedom. This end was fully achieved during the early period of Islam, the age of the pious Caliphs. Afterwards the time came to keep the sword in its sheath and engage in da‘wah work, that is, the call to God, which was the real and permanent goal of Islam. According to the explicit command of the Qur’an, the call to God is the true and eternal mission of Islam, whereas war is only temporary and allowed only in exceptional cases.
It is no exaggeration to say that Islam and violence are contradictory to each other. The concept of Islamic violence is so obviously unfounded that, prima facie it stands rejected. The fact that violence is not sustainable in the present world is enough to convince one that violence, as a principle, is quite alien to the scheme of things in Islam. Islam claims to be an eternal religion and such a religion cannot afford a principle in its scheme which will not be sustainable in later periods of human history. An attempt to bracket violence with Islam amounts to casting doubts upon the very eternity of the Islamic religion.
No wonder, then, that the Prophet Muhammad so earnestly used to entreat his Lord in his daily prayer:
“O God, You are the original source of Peace; from You is all Peace, and to You returns all Peace. So, make us live with Peace; and let us enter paradise: the House of Peace. Blessed be You, our Lord, to whom belongs all Majesty and Honour!”
