Sunan an-Nasa'i, Hadith 3836 ⓘ
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 إِسْحَاقُ بْنُ مَنْصُورٍ، قَالَ أَنْبَأَنَا عُثْمَانُ بْنُ عُمَرَ، قَالَ حَدَّثَنَا يُونُسُ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ نَذْرَ فِي مَعْصِيَةٍ وَكَفَّارَتُهُ كَفَّارَةُ يَمِينٍ " .
