It is narrated from Sayyiduna Imran bin Husayn (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "A vow made in a state of anger has no (legal) standing, and its expiation is the same as the expiation for an oath."

It is narrated from Sayyiduna Imran bin Husayn (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "A vow made in anger is not valid, and its expiation is the same as the expiation for an oath."

It is narrated from Sayyiduna Imran bin Husayn (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "A vow made in anger is not binding, and its expiation is like the expiation for an oath." And (Imam al-Hakim says that) Ma'mar narrated it from Yahya bin Abi Kathir as mu'dal (with a break in the chain).

It is narrated from Sayyiduna Imran bin Husayn (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "A vow made in disobedience to Allah has no standing (that is, it is not to be fulfilled)." Imam al-Hakim says that the narrator whom Ma'mar did not name, narrating from Yahya, is without doubt Muhammad bin al-Zubayr, because instead of saying "Banu Hanzalah" he mistakenly said "Banu Hanifah". As for his (peace and blessings be upon him) saying "There is no vow in disobedience", the two Shaykhs (Bukhari and Muslim) agree upon it, whereas the other hadith (about anger) revolves around Muhammad bin al-Zubayr al-Hanzali, and it is not authentic (in its chain).

It is narrated from Sayyiduna Imran bin Husayn (may Allah be pleased with him) that he said: Whenever the Messenger of Allah (peace and blessings be upon him) delivered a sermon to us, he commanded us in it to give charity and forbade us from "muthlah" (cutting off or disfiguring the body). And he (peace and blessings be upon him) also said: "Indeed, piercing the nose (of an animal or a person) is also part of muthlah, and a man's vowing that he will perform Hajj on foot is also muthlah (putting the body to needless hardship). So whoever has vowed to perform Hajj on foot, let him slaughter a sacrificial animal (hady) and go (for Hajj) riding." The chain of this hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.
