Hadith 15
Sayyiduna Anas (may Allah be pleased with him) reports that the Noble Prophet (peace and blessings be upon him) said: "Three things are from the morals of faith: When a person is angry, his anger should not lead him to falsehood; and when a person is happy, his happiness should not take him out of the truth; and when a person has power, he should not take that which does not belong to him."
