GUESTFRIENDSHIP.

All religions and cultures have rules regarding hospitality. They teach us to welcome strangers, and even enemies, into our homes, if they turn to us in desperate need if food, shelter or protection, and also to show kindness to strangers. Christianity, Islam, Hinduism, Judaism, Buddhism - whatever religion we practice, the laws of Hospitality are similar and have been followed for thousands of years.

In fact, back in those days when the leopard smoke, before some of these great religion existed, people in the Ancient World, such as the Greeks, had a tradition of generosity towards guests, perhaps this was because they believed that the Gods visited humans, and therefore the stranger at the gate might be a God in disguise. If the guest was not well treated and it turned out to be a God, he might destroy the host.

Turing to the present day, here is an extract from a letter from a young Christian women working in the Yemen - a Muslim country.
Hospitality is amazing here. It is one of the most important things for a person's honour. 
If you are in someone's home they are responsible for you, and treat you accordingly.
They invite you into their homes for lunch almost immediately (but) it is not just a food things; they are responsible to protect you and your family.
For example, the time a man followed me home, he was chased away by the teenage boys in the neighbourhood.
They were protecting their neighbours - me - and being hospitable.

A famous story about caring for strangers can be found in Christian teaching. It is the parable of Good Samaritan. A man lay at the side of the road to Jericho beaten and bleeding. Two men passed by him without helping, one a priest and the other an official of the Jewish temple. Along came a man from a particularly despised group of Jews, the Samaritans. The Samaritan looked after the man, took him to an inn and gave money for his ongoing care.

Offering hospitality is also fundamental to Hindu culture and providing food and shelter to a needy stranger is a traditional duty. This tradition teaches that, no matter how poor the host might be, you should always offer three items: sweet word, a place to sit, and refreshments (at least a glass of water).
It is also important to treat enemies so well that they will forget about animosity.

Hospitality in many if not all African cultures means welcoming those who are hungry, in need or oppressed in society. Being poor does not excuse anyone from providing hospitality.
According to tradition, the host also benefits from welcoming the visitors or strangers - an African proverb state, "The visitors heals the sick". This means that when a visitor comes to someone's home, family quarrels stop, the sick cheer up, peace is restored, and the home is restored to new strength.
