Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Prophet Muhammad (peace be upon him) said: "Whoever makes a picture will be punished by being told to put a soul into it, and he will not be able to put a soul into it. And whoever narrates a false dream will be made to tie two grains of barley together, and he will be punished for that. And whoever listens to people's conversations secretly while they dislike it, molten lead will be poured into his ears on the Day of Resurrection."

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "Whoever makes a picture, Allah Almighty will punish him until he breathes a soul into that picture, and he will not be able to do so. Whoever listens to people's conversation while they dislike him listening, molten lead will be poured into his ears on the Day of Resurrection. And whoever narrates a false dream will be made to tie two grains of barley together, and he will not be able to do so."

Sayyiduna Abu Huraira (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "Beware of suspicion, for suspicion is the most false of speech. Do not spy on one another. Do not try to discover each other's hidden matters. Do not envy one another. Do not distance yourselves from one another. Do not harbor malice against one another. Do not turn your faces away from one another, and be, O servants of Allah, brothers to one another."

Sayyiduna Abu Dharr Ghifari (may Allah be pleased with him) narrates this statement of the Prophet (peace and blessings be upon him): "When a person becomes angry and he is standing, he should sit down. If his anger subsides, then fine; otherwise, he should lie down."

Ahnaf bin Qais narrates the statement of his uncle, Sayyiduna Jariyah bin Qudamah (may Allah be pleased with him): He submitted, "O Messenger of Allah, tell me something by which Allah will benefit me, and tell me a brief statement so that I do not become heedless of it." The Prophet Muhammad (peace and blessings be upon him) said, "Do not become angry." He asked the Prophet (peace and blessings be upon him) the same question several times. The Prophet (peace and blessings be upon him) kept giving him the same answer every time: "Do not become angry."

Sayyiduna Jariyah bin Qudamah (may Allah be pleased with him) narrates: A man presented himself before the Prophet Muhammad (peace be upon him) and said, "Please advise me, and grant me a brief advice." The Prophet Muhammad (peace be upon him) said: "Do not get angry." That man asked you the same question again, so you said the same: "Do not get angry."

(Imam Ibn Hibban, may Allah have mercy on him, says:) The statement of the Prophet Muhammad (peace be upon him): "Do not get angry," by this he meant: After becoming angry, do not do anything from which I have forbidden you. It does not mean that the Prophet Muhammad (peace be upon him) has prohibited feeling anger, because anger is part of human nature, and it is impossible to prohibit a person from something that is inherent in his nature. Rather, this prohibition is regarding those actions that result from anger, as we have mentioned.

Sayyiduna Abdullah (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) asked: What do you call overpowering someone? The narrator says: I replied: That a person overpowers others. The Prophet Muhammad (peace and blessings be upon him) said: Overpowering (or strength) is that a person controls himself at the time of anger.

Sayyiduna Sulaiman bin Surad (may Allah be pleased with him) narrates: Two men began to argue in the presence of the Prophet Muhammad (peace and blessings be upon him). We were sitting with the Prophet (peace and blessings be upon him) at that time. One of them, in a state of anger, started abusing his companion. That person's face turned red. The Prophet (peace and blessings be upon him) said: I know of a word, if he were to say it, the anger he is experiencing would go away. That word is: "A'udhu billahi min ash-shaytan ir-rajim" (I seek refuge with Allah from the accursed devil). The people said to that man: Did you not hear what the Prophet (peace and blessings be upon him) said? He replied: I am not mad. (Meaning, I have heard it.)

Sayyiduna Abu Darda’ (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings of Allah be upon him):“On the Day of Resurrection, the heaviest thing to be recorded in the believer’s book of deeds will be good character, and Allah Almighty dislikes those who use obscene and foul language.”

Ubaidullah bin Abdullah narrates: He saw Sayyiduna Usama bin Zaid (may Allah be pleased with him) performing prayer near the blessed grave of the Prophet (peace and blessings be upon him). Marwan bin Hakam came and asked, "Are you performing prayer facing the grave?" Sayyiduna Usama bin Zaid (may Allah be pleased with him) replied, "I love the Prophet (peace and blessings be upon him)." Marwan said something bad to him and then turned away and left. Sayyiduna Usama bin Zaid (may Allah be pleased with him) finished his prayer and said, "You have hurt me. I heard the Prophet (peace and blessings be upon him) say: 'Indeed, Allah dislikes the one who uses obscene language and foul speech.' And you are one who uses obscene language and foul speech."
