Islam provides clear guidance to its followers on how people should conduct themselves in their daily lives. A Muslim is advised in the Qur'an to use the best of manners when interacting with others. The root of the word Islam is “peace,” and Muslims are to be peaceful in word and deed, treat people with kindness and mercy, and be tolerant and fair. Hypocrisy is considered to be one of the greatest of sins. Muslims embrace diversity and strive to “walk upon the earth in humility” (Qur'an 25:63).
