Caring for Non-Muslims:

The Messenger of God,(SAW) said: 'One who kills a non-Muslim whose protection is pledged,will never smell the fragrance of Jannah, even though it reaches as far as forty years distance.'(Bukhari:Ibn Umar)The mother of Asma,the daughter of Abu Bakr, was still polytheist when she came to visit Asma during the time of the Muslims' peace treaty with the Quraysh. Asma asked the Prophet,(SAW),'O Messenger of God,my mother has come to see me. Should I receive her and treat her with all the affection that is her due?'. He said,'Yes, treat her with full affection.'

(Bukhari,Muslim:Asma)
