Narrated Thabit bin ad-Dahhak (RA): that in the time of Allah's Messenger ( صلی اللہ علیہ وسلم ) a man took a vow to slaughter camels at Bawana. So, he came to Allah's Messenger ( صلی اللہ علیہ وسلم ) and asked him (about that). Allah's Messenger ( صلی اللہ علیہ وسلم ) 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] . It has a Shahid (supporting narration) from the Hadith of Kardam reported by Ahmad.
