Who was Prophet Muhammad? And what was his mission?
For us Muslims, Prophet Muhammad is the last in the series of 124,000 prophets whom God sent for guidance of human society.
Almighty God says in the Qur’ãn,
“Certainly We have sent Our messengers with clear guidance; and We sent down to them the Book and the scale so that humans may conduct themselves with justice.” (Surah al-Hadid, 57:25)
All great prophets of God –Adam to Noah, Abraham to Moses, Jesus to Muhammad– came to establish justice in society.

All humans wish for peace in this world. But peace cannot be achieved in vacuum. It is inter-twined with justice. To have peace, justice must become the foundation of our social system; otherwise, we cannot achieve a durable peace.
What is Justice?
Justice means putting everything in its rightful place; it means balancing things in the proper order; it means creating harmony. If one starts putting things in the wrong places, then he disrupts the social harmony and disturbs peace.
Peace on Personal Level
Peace in society depends on peace within ourselves. According to Prophet Muhammad: we must foster the sense of justice within ourselves by creating harmony between our emotions of anger and greed on one the hand, and our reason and intellect on the other hand; between the physical dimension and the spiritual dimension.
A just person is one who controls his anger and his greed by the power of reasoning. This act of controlling one’s anger and greed by the power of reason has been described by Prophet Muhammad as “the major jihãd”.
Once, when the Muslim army returned to Medina from its mission, the Prophet greeted the soldiers by saying, “Welcome to the people who have performed the minor jihãd, and have yet to go through a major jihãd.”
The soldiers asked, “O Prophet of God! What is the major jihãd?”
Prophet Muhammad replied, “The spiritual jihãd.”
The spiritual jihãd is not an easy jihãd. You have to gain control over your strongest emotions, and live according to the voice of reason and conscience. Only those who can conquer their egos can truly establish peace in society.
