Relations with Non-Muslims

Islam has directed us to maintain moral and social relations with the Non-Muslims.  Allah the Merciful says: 

Allah forbids you not, with regard to those who fight you not for (your) Faith nor drive you out of your homes, from dealing kindly and justly with them: for Allah loveth those who are just.  Surah Mumtahina (60:08) 

The Hadith declare that helping any person in difficulty regardless of religion or race brings us reward.  Helping Non-Muslims who are facing difficulties and spending on needy poor has been a longstanding habit of Muslims.  An example of what the Beloved Prophet (Sallallahu alaihi wa sallam) did, so that they acquire this habit is given in this Hadith: 

Translation of Hadith: A year, the people of Makkah suffered a famine.  The Pure Messenger (Sallallahu alaihi wa sallam) sent 500 Dirhams to Abu Sufyan Bin Harb and 500 Dirhams to Safwan bin Ummayya to distribute among the needy.  (Radd ul Muhtaar, Vol. 2, Pg. No: 92)  

The amount of Zakaat cannot be spent on the Non-Muslims, they can be helped with other optional charities.  

Imam Bukhari has recorded a Hadith in his great collection of Hadith, Sahih Bukhari, Kitab ul Jizya.  

The Messenger of Allah (Sallallahu alaihi wa sallam) has described dire warnings when a Muslim murders a non-Muslims.  It is given in Sahih Bukhari, Kitab Ul Jizya, Hadith No: 2930:

Translation of Hadith: It is narrrated on the authority of Hadhrat Abdullah bin 'Amr (May Allah be well pleased with him) that the Beloved Prophet (Sallallahu alaihi wa sallam) said: Whoever murders a non-Muslims with whom there was a pact, that person will not even get the fragrance of Jannah, even though its fragrance can be smelled from a distance of 40 years.  

This shows that Islam is the true religion, which promotes peace and brotherhood in the world.
