While Islam presents itself as the only way of life for people to achieve salvation in the after-life, it also teaches its followers to live up to high standards in conduct with other human beings, regardless of their religion, ethnicity, race, language or culture. The Holy Quran is highly critical of Christian beliefs in Trinity and regarding Jesus (peace be on him) as a deity. The Holy Book is also very critical of the Jews for not accepting Jesus and Muhammad (peace be on them) as messengers of God. At the same time, however, it asks Muslims to establish a social association special only to Christians and Jews. Examples of such association are permission of marrying chaste women among them and giving explicit permission to eat their food.
The verses in the Holy Quran forbid Muslims to insult anything that is viewed as a deity by any religion, regardless of whether it is a person, a stone, a stick or a tree. The verse 2:256 of the Quran says:
Let there be no compulsion in religion: Truth stands out clear from Error: whoever rejects evil and believes in Allah has grasped the most trustworthy hand-hold, that never breaks. And Allah hears and knows all things.
Islam wants its adherents to be just to every human being.
"Do not let your hatred of a people incite you to aggression." (The Quran 5:2).
"And do not let ill-will towards any folk incite you so that you swerve from dealing justly. Be just; that is nearest to heedfulness" (The Quran 5:8).
Muslims are asked to be truthful, trustworthy, humble, kind and generous. They are asked to repel evil with goodness, control their anger, and be forgiving. Some of the sayings of the Prophet are:
"To remove something harmful from the road, is charity."
"Charity erases sins just as water extinguishes fire."
"He is not a perfect believer, who goes to bed full and knows that his neighbor is hungry."
"Show mercy to people on earth so that Allâh will have mercy on you in heaven."
