From an Islamic point of view there is a hadith (narration from the Messenger Muhammad (peace and blessings be upon him) related to good companionship (and its effects) and bad companionship (and its effects).
Abu Musa Al-Ash`ari (may Allah be pleased with him) reported that the Prophet (peace and blessings be upon him) said,
"The example of a good companion and that of a bad companion is like that of the bearer of musk and the worker on the bellows. A bearer of musk will give you some, or you might buy some from him, or you might at least enjoy the fragrance of his musk. However, the worker on the bellows, on the other hand, might spoil your clothes with sparks from his bellows, or you will at least get a bad smell from him."
[Reported by Al-Bukhari and Muslim, this version being Muslim's]
So you should choose your friends wisely as there will be some companions or friends who will exhort and command you to do good, like prayer, charity, speaking the truth, being sincere and honest, etc. and there will be some who command or encourage you to do bad or evil, such as disrespecting people, backbiting, lying, using foul language.
The effects of each type of companion will rub on to an individual as alluded to by the hadith. So choose your friends wisely!
That translation appears in the "NIV":"Do not be misled: 'Bad company corrupts good character.'" (I Cor.15:33)The wording of the "KJV" says:"Be not deceived: evil communications corrupts good manners."
Evil communications can corrupt good manners by influencing individuals to engage in inappropriate or unethical behavior. Exposure to negative influences can desensitize individuals to harmful actions, leading them to adopt behaviors that go against their moral compass. Over time, continued exposure to such communication can erode one's sense of right and wrong, ultimately corrupting their good manners.
Johann Wolfgang von Goethe
It means the bad things a man does or bad manners he has are always remembered while the good things are quickly forgotten.
good manners=behavior
That depends on the people with whom one associates. Many have no idea what good manners are or how they would act in polite society. For them, good manners mean nothing. For people who understand manners and courtesy, yes; manners are "in".
The name for good manners is 'Etiquette.'
There is no single accepted code of good manners because good manners, or etiquette, depends on both the culture and situation.
