عَنْ عَائِشَةَ قَالَتْ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا نَذْرَ فِي مَعْصِيَةٍ وَكَفَّارَتُهُ كَفَّارَةُ الْيَمِينِ» . رَوَاهُ أَبُو دَاوُدَ وَالتِّرْمِذِيُّ وَالنَّسَائِيّ
Translation

‘Amr b. Shu'aib, on his father’s authority, said that his grandfather told of a woman who said, “Messenger of God, I have taken a vow to play the tambourine over you,” to which he replied, “Fulfil your vow.” Abu Dawud transmitted it.Razin added that she said, “And I have taken a vow to perform a sacrifice in such and such a place,” a place in which people had performed sacrifices in pre-Islamic times. He asked whether that place contained any idol worshipped in pre-Islamic times, and she replied that it did not. He asked whether any pre-Islamic festival was observed there, and she replied that none was. He then said, “Fulfil your vow.”Razin
