Good manners

Q 3: I heard that the heaviest attribute placed in one's Mizan (the Scales for weighing deeds) is good manners. I thought that good manners meant to treat the people with kindness and tolerance, but someone told me that they refer to Tawhid (belief in the Oneness of Allah). Is this correct?

A: Good manners means to treat people kindly in words and deeds, engage in good deeds, refrain from hatred, and not offend anyone.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
