When Prophet Muhammad (a) declared himself to be the Messenger of Allah, the people of Arabia were leading a very miserable life. They were rough and ignorant people who were not conversant with the decorum of a civilized society. So much so that they did not care even to seek permission before entering another’s house and did not wish each other when they met. They considered themselves to be enemies of each other and spoke in a very harsh tone. The Holy Prophet gradually taught them the rules of social behaviour and the principles of civilization and culture.
During the last fourteen centuries, man has made great progress in different walks of life. Education has become very common and modern means of transport have made the world much narrower. However, the universal and eternal Islamic principles of civilization continue to guide humanity. We mention below some of them which are well-known as well as very important for our social life.
If we intend entering somebody’s house or room and the door is shut, we should knock at the door gently with a view to seeking permission to enter.
If we happen to meet some acquaintances in a gathering or in a street, we should wish them by saying “Salamun Alaikum”.
While walking in a street, we should be careful not to bump into anyone. In case we form part of a crowd, we should walk behind one another so that we do not block the way of others.
It is necessary for us not to disturb others. When others are sleeping, we should remain quiet and should not disturb their sleep by making noise.
Most of us are well aware of these rules and principles but are usually negligent in observing them. However, to lead a pleasant social life, it is incumbent upon us to understand these principles properly and to act upon them to the best of our ability.
Islam teaches us the best social etiquette.
