أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ الْمُبَارَكِ الْمُخَرِّمِيُّ، قَالَ حَدَّثَنَا يَحْيَى بْنُ آدَمَ، قَالَ حَدَّثَنَا ابْنُ الْمُبَارَكِ، عَنْ يُونُسَ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ، قَالَتْ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ نَذْرَ فِي مَعْصِيَةٍ وَكَفَّارَتُهُ كَفَّارَةُ يَمِينٍ " .
It was narrated that 'Aishah said: "The Messenger of Allah said: 'There is no vow to commit an act of disobedience, and its expiation is the expiation for an oath.'"
