Mustaʾmīn or Musta'man is a historical Islamic term for a non-Muslim foreigner temporarily residing in Muslim lands with aman, or guarantee of short-term safe-conduct (aman mu'aqqat), affording the protected status of dhimmi (non-Muslim subjects permanently living in a Muslim-ruled land) without the payment of jizya. Merchants, messengers, students and other groups could be given an aman, while foreign envoys and emissaries were automatically protected.

Types of safe-conducts

The short-term safe-conduct can be personal or general: The term is valid up to one year for the musta'min, along with his minor children and all the women related to him. Many Hanbalite jurists allowed the period of aman to one lunar year. Others argued for an indefinite aman.

Legal rights

Once given aman, the musta'mins are free to engage in trade and travel. They are allowed to bring their family and children. They have permission to visit any city in Muslim territory except the holy cities of Mecca and Medina. A musta'min man is allowed to marry a dhimmi woman and take her back to his homeland; however, musta'min women do not have the same right. The musta'min are subject to civil and criminal law in the territory and may not do or say anything that could be construed as harming the interests of Islam. If caught doing so, the musta'min could be expelled or executed and the aman grantor could also be penalized.
