It was narrated from 'Aishah that the Messenger of Allah said: "There is no vow to commit an act of disobedience and its expiation is the expiation for an oath."
أَخْبَرَنَا يُونُسُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ نَذْرَ فِي مَعْصِيَةٍ وَكَفَّارَتُهُ كَفَّارَةُ الْيَمِينِ " .
