The Holy Quran, Sūrat l-māidah 5:16
God guides with it whoever follows His approval to the ways of peace,
and He brings them out of darkness into light, by His permission, and
He guides them in a straight path.
The Holy Quran, Sūrat l-fur'qān 25:47-56
And it is He who made the night a covering for you, and sleep for
rest; and He made the day a revival. And it is He who sends the winds,
bringing advance news of His mercy; and We send down from the sky pure
water. To revive dead lands thereby, and to provide drink for the
multitude of animals and humans We created. We have circulated it
among them, that they may reflect, but most people persist in
thanklessness. Had We willed, We could have sent to every town a
warner. So do not obey the disbelievers, but jihad them with it, a
mighty jihad. And it is He who merged the two seas; this one fresh
and sweet, and that one salty and bitter; and He placed between them a
barrier, and an impassable boundary. And it is He who, from fluid,
created the human being. Then He made relationships through marriage
and mating. Your Lord is Omnipotent. And yet, instead of God, they
serve what neither profits them nor harms them. The disbeliever has
always turned his back on his Lord. We sent you only as a herald of
good news and a warner.
How does this part of the Quran begin? It is a picture of harmony, a harmony created by Him.
In contrast to old polytheist myths (e.g. Sumeric/Accadic and Greek), where the beginning of the world is described by a war between different deities, we got to know that God prepared the world in harmony. The original state of the world is harmony, not war.
In the middle of the text, we find the verse "So do not obey the disbelievers, but jihad them with it in a mighty jihad." where I left the word jihad untranslated. "with it" refers to the Message of God, in particular the Quran. We shall jihad with the Word of God.
God sent His messenger (p.b.u.h) because they do not recognise His magnificent work, only as a herald of good news and a warner.
As the initial state of the world is peace, the initial state for humans living side by side is peace, not war. A peace treaty is not required when there has been no war. What is commanded is jihad with the Word of God. The Word of God is not the sword, and jihad by the Word is underlined by an exemplary goodness of the one who gives the message. And it will not convince anybody if it is said by someone who from the beginning on is hostile. Who should then accept the message of Allah, the Most Merciful, the Most Compassionate? Who would then read the Quran until the 41st Sura, saying:
The Holy Quran, Sūrat fuṣṣilat 41:30-34
Surely, those who say: “Our Lord is God,” and then go straight, the
angels will descend upon them: “Do not fear, and do not grieve, but
rejoice in the news of the Garden which you were promised. We are your
allies in this life and in the Hereafter, wherein you will have
whatever your souls desire, and you will have therein whatever you
call for. As Hospitality from an All-Forgiving, Merciful One.” And who
is better in speech than someone who calls to God, and acts with
integrity, and says, “I am of those who submit”? Good and evil are not
equal. Repel evil with good, and the person who was your enemy becomes
like an intimate friend.
