dear Donosa, here are some teachings for the Muslims about good manners and good character, extra for you:

Narrated 'Abdullah bin 'Amr: "The Prophet never used bad language neither a 'Fahish nor a Mutafahish. He used to say 'The best amongst you are those who have the best manners and character.' (Translation of Sahih Bukhari, Virtues and Merits of the Prophet (peace be upon him) and his Companions, Volume 4, Book 56, Number 759)"

"Allah forbids you not, With regard to those who Fight you not for (your) Faith Nor drive you out Of your homes, From dealing kindly and justly With them: For Allah loves Those who are just. (The Noble Quran, 60:8)"

Narrated Jarir bin 'Abdullah: "Allah's Apostle said, 'Allah will not be merciful to those who are not merciful to mankind.' (Translation of Sahih Bukhari, ONENESS, UNIQUENESS OF ALLAH (TAWHEED), Volume 9, Book 93, Number 473)"

The Muslim needs to always be polite, humble, patient, loving and well mannered when he/she deals with others, whether they were Muslims or non-Muslims. Allah Almighty certainly doesn't love those who are offensive and rude to others.

Narrated Abu Huraira: "Allah's Apostle said, "Anybody who believes in Allah and the Last Day should not harm his neighbor, and anybody who believes in Allah and the Last Day should entertain his guest generously and anybody who believes in Allah and the Last Day should talk what is good or keep quiet. (i.e. abstain from all kinds of evil and dirty talk). (Translation of Sahih Bukhari, Good Manners and Form (Al-Adab), Volume 8, Book 73, Number 47)"

Allah Almighty commands us not to be stuck-up. He commands us to be laid back and down to earth type of people.

Let us look at Noble Verse 17:37 "Nor walk on the earth with insolence: for thou can not rend the earth asunder, nor reach the mountains in height."

"And swell not thy cheek (for pride) at men, nor walk in insolence through the earth; for God loves not any arrogant boaster. (The Noble Quran, 31:18)"

"O ye who believe! Let not some men among you laugh at others: It may be that the (latter) are better than the (former): Nor let some women laugh at others: It may be that the (latter are better than the (former): Nor defame nor be sarcastic to each other, nor call each other by (offensive) nicknames: Ill-seeming is a name connoting wickedness, (to be used of one) after he has believed: And those who do not desist are (indeed) doing wrong. (The Noble Quran, 49:11)"

"And that you be dutiful to your parents. If one of them or both of them attain old age in your life, say not to them a word of disrespect, nor shout at them but address them in terms of honor. And lower unto them the wing of submission and humility through mercy, and say: "My Lord! Bestow on them Your Mercy as they did bring me up when I was small." (17:23, 24)

And those are only a very few teachings of Islam
