باب مَنْ قَالَ كَفَّارَتُهَا تَرْكُهَا
Sunan Ibn Majah, Book of The Expiation(view book)
It was narrated from 'Aishah that the Messenger of Allah ﷺ said:
"Whoever takes an oath to cut off the ties of kinship, or to do something that is not right, the fulfillment of his vow is not to do that."
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ، عَنْ حَارِثَةَ بْنِ أَبِي الرِّجَالِ، عَنْ عَمْرَةَ، عَنْ عَائِشَةَ، قَالَتْ قَالَ رَسُولُ اللَّهِ ﷺ " مَنْ حَلَفَ فِي قَطِيعَةِ رَحِمٍ أَوْ فِيمَا لاَ يَصْلُحُ فَبِرُّهُ أَنْ لاَ يَتِمَّ عَلَى ذَلِكَ " .

It was narrated from 'Amr bin Shu'aib, from his father, that his grandfather said that the Prophet ﷺ said:
"Whoever swears an oath then sees that something else is better than it, let him not do it, and his leaving it is the expiation for it. "
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الْمُؤْمِنِ الْوَاسِطِيُّ، حَدَّثَنَا عَوْنُ بْنُ عُمَارَةَ، حَدَّثَنَا رَوْحُ بْنُ الْقَاسِمِ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، . أَنَّ النَّبِيَّ ﷺ قَالَ " مَنْ حَلَفَ عَلَى يَمِينٍ فَرَأَى غَيْرَهَا خَيْرًا مِنْهَا فَلْيَتْرُكْهَا فَإِنَّ تَرْكَهَا كَفَّارَتُهَا " .
