(Allah's Messenger (SAW) said) "There is no fulfillment of a vow involving an act of disobedience." [Reported by Muslim].

‘Imran b. Husain reported God's Messenger as saying, “A vow to do an act of disobedience must not be fulfilled, or one to do something over which one has no control.” Muslim transmitted it. A version has, “No vow must be taken to disobey God.”

that in the time of Allah's Messenger (SAW) a man took a vow to slaughter camels at Bawana. So, he came to Allah's Messenger (SAW) and asked him (about that). Allah's Messenger (SAW) asked, "Did the place contain any idol which was worshiped (during Jahiliyya era)?" He said, "No." He asked "Were any of their (Jahiliyya) festivals observed there?" He said, "No." He then said (to the man), "Fulfill your vow, for there is no fulfillment of a vow to do an act of disobedience to Allah, now to break the ties of relationship, nor to do something over which a human being has no control." [Reported by Abu Dawud and at-Tabarani, and the wording is his (at-Tabarani). It has a sound chain of narrators].

Thabit b. ad-Dahhak said that in the time of God's Messenger a man took a vow to slaughter camels at Buwana and came and told him. God’s Messenger asked whether the place contained any idol worshipped in pre-Islamic times and was told that it did not. He asked whether any pre-Islamic festival was observed there and was told that no such thing was observed. He then said to the man, “Fulfil your vow, for a vow to do an act of disobedience to God must not be fulfilled, neither must one to do something over which a human being has no control.” Abu Dawud transmitted it.

In the time of the Prophet (saws) a man took a vow to slaughter a camel at Buwanah. So he came to the Prophet (saws) and said: I have taken a vow to sacrifice a camel at Buwanah.

The Prophet (saws) asked: Did the place contain any idol worshipped in pre-Islamic times?

They (the people) said: No.

He asked: Was any pre-Islamic festival observed there?

They replied: No.

The Prophet (saws) said: Fulfil your vow, for a vow to do an act of disobedience to Allah must not be fulfilled, neither must one do something over which a human being has no control.

Muhammad. He came near him and said: What is the matter with you? Thereupon he (the prisoner) said: Why have you taken me as prisoner and why have you caught hold of one proceeding the pilgrims (the she-camel as she carried the Holy Prophet on her back and walked ahead of the multitude)? He (the Holy Prophet) said: (Yours is a great fault). I (my men) have caught hold of you for the crime of your allies, Banu Thaqif. He (the Holy Prophet) then turned away. He again called him and said: Muhammad, Muhammad, and since Allah's Messenger (may peace be upon him) was very compassionate, and tenderhearted, he returned to him, and said: What is the matter with you? He said: I am a Muslim, whereupon he (the Holy Prophet) said: Had you said this when you had been the master of yourself, you would have gained every success. He then turned away. He (the prisoner) called him again saying: Muhammad, Muhammad. He came to him and said: What is the matter with you? He said: I am hungry, feed me, and I am thirsty, so provide me with drink. He (the Holy Prophet) said: That is (to satisfy) your want. He was then ransomed for two persons (who had been taken prisoner by Thaqif). He (the narrator) said: A woman of the Ansar had been taken prisoner and also al-Adbi' was caught. The woman had been tied with ropes. The people were giving rest to their animals before their houses. She escaped one night from the bondage and came to the camels. As she drew near the camels, they fretted and fumed and so she left them until she came to al-, Adbi'. It did not fret and fume; it was docile She rode upon its back and drove it away and she went off. When they (the enemies of Islam) were warned of this, they went in search of it, but it (the she-camel) exhausted them. She (the woman) took vow for Allah, that in case He would save her through it, she would offer that as a sacrifice. As she reached Medina, the people saw her and they said: Here is al-Adbi, the she-camel of Allah's Messenger (may peace be upon him). She (the woman) said that she ...

'Adba belonged to a man of Banu 'Aqil. It used to go ahead of pligrims. The man was then captivated. He was brought in chains to the Prophet (saws). The Prophet (saws) was riding on a donkey with a blanket on him. He said: Muhammad, why do you arrest me and capture the one (i.e. the she-camel) which goes ahead of the pilgrims. He replied: We are arresting you on account of the crime committed by your allies Thaqid. Thaqif captivated two persons from among the Companions of the Prophet (saws). He said (whatever he said) I am a Muslim, or he said: I have embraced Islam. When the Prophet (saws) went ahead, he called him: O Muhammed, O Muhammed. Abu Dawud said: I learnt it from the version of the narrator Muhammad b. 'Isa. The Prophet (saws) was compassionate and kind hearted. So he returned to him, and asked: What is the matter with you ? He replied: I am a Muslim. He said: Had you said it when the matter was in your hand, you would have succeeded completely. Abu Dawud said: I then returned to the version of the narrator Sulaiman (b. Harb). He said: Muhammad, I am hungry, so feed me. I am thirsty, so give me water. The Prophet (saws) said: This is your need, or he said: This is his need (the narrator is doubtful). Later on the man was taken back (by Thaqif) as a ransom for the two men (of the Companions of the Prophet). The Prophet (saws) retained 'Adba for his journey. The narrator said: The polytheists raided the pasturing animals of Medina and they took away 'Adba. When they took away 'Adba, they also captivated a Muslim woman. They used to leave their camels in the fields for rest at night. One night they slept and the (Muslim) woman stood up. Any camel on which she put her hand brayed until she came to 'Adba. She came to a she-camel which was docile and experienced. She then rode on her and vowed to Allah that if He saved her, she would sacrifice it. When she came to Medina, the people recognized the she-camel of the Prophet (saws). The Prophet (saws) was then informed about it and he sent for her. She was brought to him and she informed him about her vow. He said: It is a bad return that you have given it. Allah has not saved you, on its (back) that you now sacrifice it. A vow to do an act of disobedience must not be fulfilled, or to do something over which one has no control.

Abu Dawud said: This woman was the wife of Abu Dharr.
