Islam and Non-Muslims
Islam protects the lives, wealth and honor of non-Muslims who have a pact with an Islamic nation. They may not be oppressed nor transgressed against. They may not be deprived of their rights, nor ill-treated in dealings.
Allah says: 
Allah does not forbid you from being righteous and just toward those who do not fight you because of religion and do not expel you from your homes. Indeed, Allah loves those who act justly 
(60:8)
The Messenger of Allah, Muhammad 
said: “Indeed whoever oppresses one with whom we have a pact, deprives him of his rights, burdens him with more than he can bear, or takes something from him without his consent, then I will dispute with him on the Day of Requital.” (Abu Dawud)
He then pointed with his finger to his chest. “Indeed whoever kills one with whom we have a pact, who is under the protection of Allah and His Messenger, Allah will forbid him from smelling the fragrance of Jannah (Heavenly Gardens), and indeed the fragrance of Jannah may be perceived from a distance of seventy years.” (Sakhawy – Maqasid al-Hasinah)
The Messenger of Allah, Muhammad said: “My Lord has commanded me that we should not oppress the ones with whom we have entered into a pact (non-Muslims who reside in the lands of the Muslims) or anyone else.” (Baihaqi)
