Abu Huraira and Ibn ‘Umar reported God’s Messenger as saying, “Do not make vows, for a vow has no effect against fate; it is only from the miserly that it is a means by which something is extracted.”
‘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.”
Narrated Abul Ahwas ‘Auf b. Malik quoted his father as saying:
I said, “Messenger of God, tell me what I should do about a cousin of mine to whom I go and ask for something, but who neither gives me anything nor regards my kinship, then when he needs my help comes to me and asks for something, and I have sworn that I would not give him anything or regard his kinship.” He commanded me to do that which is better and make atonement for my oath.
In Ibn Majah’s version he told that he said, “Messenger of God, my cousin comes to me and I swear that I will not give him anything or regard his kinship,” and that he replied, “Make atonement for your oath.”
