One who swears to refrain from something and then does it (that thing), or swears to do something and then does not do it, is bound to expiate for that broken oath. 1531 Expiation is not required if one says “Inshallah (Allah willing),” connected with the oath without separation, or if one does it under coercion or out of forgetfulness. 1532
وَمَنْ حَلَفَ أَلاَّ يَفْعَلَ شَيْئًا، فَفَعَلَهُ، أَوْ لَيَفْعَلَنَّهُ فِيْ وَقْتٍ، فَلَمْ يَفْعَلْهُ فِيْهِ، فَعَلَيْهِ كَفَّارَةُ يَمينٍ، إِلاَّ أَنْ يَقُوْلَ: إِنْ شَاءَ اللهُ مُتَّصِلاً بِيَمِيْنِهِ، أَوْ يَفْعَلَهُ مُكْرَهًا أَوْ نَاسِيًا، فَلاَ كَفَّارَةَ عَلَيْهِ.
