The Prophet (may Allah's peace and blessings be upon him) informed us that he guarantees a house in the surroundings of Paradise for the one who refrains from arguing even if he is right, because arguing is a waste of time and causes enmity and hatred among people. He also guarantees a house in the middle part of Paradise for the one who refrains from lying even if he is joking and a house in the highest part of Paradise for the one who improves and perfects his manners by striving to discipline himself.
