What is the ruling on one who kills a disbeliever who has entered the lands of the Muslims under a guarantee of safety?

Question:
May Allah reward you, Honorable Shaykh. This questioner asks: What is the ruling on one who kills a disbeliever who has entered the lands of the Muslims under a guarantee of safety?

Answer:
The ruling is that he is a traitor, a traitor, may Allah protect us from that, and he falls under the saying of the Messenger (peace and blessings be upon him): "Whoever kills a person under a treaty will not smell the fragrance of Paradise, even though it is forty miles away" , narrated by al-Bukhari. The musta'min (a non-Muslim granted safe conduct) falls under the category of the mu'ahad (one under a treaty) because he entered under a guarantee of safety, and the Muslims' guarantee is upheld by their ears and tongues; safety is valid from every Muslim, based on the saying of the Messenger (peace and blessings be upon him): "A woman granted safety to a disbeliever, and the Messenger (peace and blessings be upon him) granted him safety" . So the one who kills him is a traitor and a sinner. The matter of his proceedings is to be referred to the ruler, to the one in authority. Yes.
