It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him), he states: I heard the Messenger of Allah (peace and blessings be upon him) say: "A vow is like an oath, and its expiation is the expiation for an oath."

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: "There are two types of vows. __QUR_N__ One vow is for Allah, its expiation is to fulfill it, and one vow is for Satan, it should not be fulfilled, but the expiation of an oath will be due upon it."

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said: "A vow is only that by which the pleasure of Allah, the Exalted, is sought."

It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) that the wife of Sayyiduna Abu Dharr (may Allah be pleased with him) came riding on the mount of the Messenger of Allah (peace and blessings of Allah be upon him), "Qaswa", until she made it sit near the mosque and said: O Messenger of Allah! I had vowed that if Allah Almighty saved me upon this, then I would surely eat from its liver and hump. The Prophet (peace and blessings of Allah be upon him) said: "You have given it a very bad reward. This is not a vow; a vow is only that by which Allah's pleasure is sought."

It is narrated from Sayyiduna Thabit bin Dhahak (may Allah be pleased with him), he states that in the time of the Noble Prophet (peace and blessings of Allah be upon him), a man made a vow to slaughter a camel at the place of Buwana. He came to the Messenger of Allah (peace and blessings of Allah be upon him) and said: I have made a vow to slaughter a camel at the place of Buwana. The Messenger of Allah (peace and blessings of Allah be upon him) asked him: "Is there any idol from the idols of the time of ignorance there, which is worshipped?" He said: No. The Prophet (peace and blessings of Allah be upon him) said: "Is there any festival from among their (the polytheists') festivals celebrated there?" He said: No. The Prophet (peace and blessings of Allah be upon him) said: "Fulfill your vow. For there is no vow in disobedience to Allah, in severing ties of kinship, or in that which the son of Adam does not possess."

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "Allah Almighty said: The vow of the son of Adam does not bring him anything except what I have already decreed for him. A vow is such a thing that through it I extract wealth from the miser. Because of it, he gives me (wealth) which (in normal circumstances) he would not give due to his miserliness." And in another narration: "Which he had not given Me before."

Sayyiduna Uqbah bin Amir Juhani (may Allah be pleased with him) says: My sister made a vow that she would walk barefoot and bareheaded towards the Ka'bah. The Prophet (peace and blessings of Allah be upon him) came to her and said: "What is the matter with her?" The people said: She has made a vow that she will walk barefoot and bareheaded towards the Ka'bah. He said: "Order her to ride, to cover herself with a cloak, to perform Hajj, and to slaughter a sacrifice."
