Narrated Thabit bin ad-Dahhak (RA):

that in the time of Allah's Messenger (ﷺ) a man took a vow to slaughter camels at Bawana. So, he came to Allah's Messenger (ﷺ) and asked him (about that). Allah's Messenger (ﷺ) 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].

وَعَنْ ثَابِتِ بْنِ اَلضَّحَّاكِ ‏- رضى الله عنه ‏- قَالَ: { نَذَرَ رَجُلٌ عَلَى عَهْدِ رَسُولِ اَللَّهِ ‏- صلى الله عليه وسلم ‏-أَنْ يَنْحَرَ إِبِلاً بِبُوَانَةَ, فَأَتَى رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-فَسَأَلَهُ: فَقَالَ: "هَلْ كَانَ فِيهَا وَثَنٌ يُعْبَدُ ?" .‏ قَالَ: لَا.‏ قَالَ: "فَهَلْ كَانَ فِيهَا عِيدٌ مِنْ أَعْيَادِهِمْ ?" فَقَالَ: لَا.‏ [1]‏ فَقَالَ: "أَوْفِ بِنَذْرِكَ; فَإِنَّهُ لَا وَفَاءَ لِنَذْرٍ فِي مَعْصِيَةِ اَللَّهِ, وَلَا فِي قَطِيعَةِ رَحِمٍ, وَلَا فِيمَا لَا يَمْلِكُ اِبْنُ آدَمَ" } رَوَاهُ أَبُو دَاوُدَ, وَالطَّبَرَانِيُّ وَاللَّفْظُ لَهُ, وَهُوَ صَحِيحُ اَلْإِسْنَادِ.‏ [2]‏
