Islam orders Muslims to deal kindly and justly to all non Muslims as long as they do not oppose or oppress Muslims or place obstacles in the way of spreading Islam.
“And had your Lord willed, those on earth would have believed, all of them together. So, will you (O Muhammad) then compel mankind, until they become believers.” (Yunus:99)
“Verily, those who believe (in Allah and in His Messenger Muhammad), and those who are Jews, and the Sabians, and the Christians, and the Magians, and those who worship others besides Allah, truly, Allah will judge between them on the Day of Resurrection. Verily! Allah is Witness over all things.”(Al-Haj:17)
Our Noble Prophet, peace and blessings be upon him, said: “Beware the supplication of the oppressed, for indeed there is no barrier between it and Allaah” (Al-Bukhari)
Actually the general rule that Muslims should follow when dealing with non-Muslims is based of the verse: “Allah does not forbid you to deal justly and kindly with those who fought not against you on account of religion and did not drive you out of your homes. Verily, Allah loves those who deal with equity. It is only as regards those who fought against you on account of religion, and have driven you out of your homes, and helped to drive you out, that Allah forbids you to befriend them. And whosoever will befriend them, then such are the Zalimun (wrong-doers those who disobey Allah).” (Surah60:8-9)
