The Holy Prophet (PBUH) as the last divine messenger is considered a mercy for all the worlds so that his attribute of kindness and compassion overcomes all his other characteristics. In his view, all human beings have a respectable soul and they cannot be destroyed. As in the behavior and practical life of the Prophet (PBUH) this method can be seen clearly. Some people, based on weak and unreliable reports, are trying to equate the killing of some of his opponents and enemies with the method of terrorism. The results of this article by descriptive-analytical method indicate that in addition to the weakness of the document and the unreliability of such reports, there is evidence in their text that shows that their killing is by no means an assassination in the modern sense. On the other hand, the Prophetic biography (PBUH) was always based on tolerance and kindness to the opponents and did not fight the enemies as much as possible.
