Having a good character and performing good deeds is so important in Islam.
Prophet Muhammad (peace be upon him) taught us to carry out good deeds, no matter how small they are. In Islam, even a smile to a neighbour Or removing a harmful object from the road, is classed as an act of charity. Abu Huraira (may allah be pleased with him) reported that the Prophet, may Allah bless him and grant him peace, said: "A man passed by a fallen branch in the middle of the road and said, 'By Allah, I will remove this from the path of the Muslims so that it does not inconvenience them' and he was admitted into the Garden (Paradise)." (recorded in Muslim).
The Prophet Muhammad (peace be upon him) continuously insisted on people treating others correctly. The following hadith (sayings of the Prophet) are a few of his sayings regarding our behaviour towards others:
"By Allah, he does not believe! By Allah, he does not believe! By Allah, he does not believe!" It was said, "Who is that, O Allah's Apostle?" He said, "That person whose neighbour does not feel safe from his evil." (Bukhari)
“The best of people are those that bring most benefit to the rest of mankind.” (Daraqutni, Hasan).
"Anybody who believes in Allah and the Last Day should not harm his neighbour, 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).'' (Bukhari)
“The best of you are those who are best to their families, and I am the best of you to my family.” (Tirmidhi, Sahih).
