The root word in Arabic for MAN is 'INS' إنس.The word 'UNS' أٌنس means 'sociable', 'sociability'. Man, by nature, is a social being; i.e. he lives in a society, is dependent upon it. Without a society, human lives would be difficult. So much to say, it is the duty of each & every person on earth, to contribute for the well being of the society & to keep a good relationship with other fellow human beings.

Whoever fulfilled the needs of his brother, Allaah will fulfill his needs; whoever brought his (Muslim) brother out of a discomfort, Allaah will bring him out of the discomforts of the Day of Resurrection, and whoever screened a Muslim, Allaah will screen him on the Day of Resurrection." [Bukhari]
