Islam lays much importance on courteous behaviour and also explains and stresses its different aspects. To meet people cheerfully, to avoid causing trouble to them, rather to try to make things convenient and comfortable to them, to do social service, to extend co-operation to others in good things and to be generous, and to like for others also that you like for yourself, are all forms of moral behaviour that are counted as virtues in Islam. All that is bad and vicious is considered by Islam as sinful. This Hadith describes two signs of a sin. First, man should feel scruples in committing it. Second, one does not like others being informed about it. The Hadith further tells us that human nature leads man to correct conclusions and keeps him away from evils, provided it has not been deformed by the environment and bad company.
