I have heard conflicting information on what place a Non-Muslim holds in a Muslim's life. Are they brothers/sisters, or are they infidels to be avoided? Is a Muslim allowed to be friends or maintain acquaintance with a non-Muslim? Can a Muslim work for a Non-Muslim? Can a Muslim employ a non-Muslim? i.e. Are there provisions for discrimination against non-Muslims?
I have heard that there is some difference in how you treat people of the book (i.e. Christians, Jews) vs. Idol-worshipers (Hindus, etc.). Is that true, or is that just limited to certain things such as marriage?
Are Muslims allowed to maintain acquaintance with people who have rejected Islam (Kafir)?
