"By Allah, if anyone of you insists on fulfilling an oath by which he may harm his family, he commits a greater sin in Allah's sight than that of dissolving his oath and making expiation for it."  

رَسُولُ اللَّهِ ﷺ وَاللَّهِ لأَنْ يَلِجَّ أَحَدُكُمْ بِيَمِينِهِ فِي أَهْلِهِ آثَمُ لَهُ عِنْدَ اللَّهِ مِنْ أَنْ يُعْطِيَ كَفَّارَتَهُ الَّتِي افْتَرَضَ اللَّهُ عَلَيْهِ  

This is what Abu Huraira reported to us from Messenger of Allah ﷺ, and he narrated a hadith and (one) of them is that Messenger of Allah ﷺ said: I swear by Allah, it is more sinful in Allah's sight for one of you to persist in an oath regarding his family than payment of its expiation which Allah has imposed upon him (for breaking the oath).  

عَنْ رَسُولِ اللَّهِ ﷺ فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ ﷺ وَاللَّهِ لأَنْ يَلَجَّ أَحَدُكُمْ بِيَمِينِهِ فِي أَهْلِهِ آثَمُ لَهُ عِنْدَ اللَّهِ مِنْ أَنْ يُعْطِيَ كَفَّارَتَهُ الَّتِي فَرَضَ اللَّهُ  

"By Allah, if anyone of you insists on fulfilling an oath by which he may harm his family, he commits a greater sin in Allah's sight than that of dissolving his oath and making expiation for it." (Using translation from Bukhārī 6625)  

وَقَالَ رَسُولُ اللهِ ﷺ وَاللهِ لَأَنْ يَلَجَّ أَحَدُكُمْ بِيَمِينِهِ فِي أَهْلِهِ آثَمُ لَهُ عِنْدَ اللهِ مِنْ أَنْ يُعْطِيَ كَفَّارَتَهُ الَّتِي فَرَضَ اللهُ ﷻ  

[Machine] The Messenger of Allah ﷺ said, "By Allah, it is more sinful for one of you to enter upon his family with his right hand than to give his required expiation that Allah has obliged."  

وَقَالَ رَسُولُ اللهِ ﷺ وَاللهِ لَأَنْ يَلِجَ أَحَدُكُمْ بِيَمِينِهِ فِي أَهْلِهِ آثَمُ لَهُ عِنْدَ اللهِ مِنْ أَنْ يُعْطِيَ كَفَّارَتَهُ الَّتِي فَرَضَ اللهُ  

" إِذَا اسْتَلَجَّ أحدُكم في اليمينِ وفي لفظٍ: اليمين في أهْله- فإنَّهُ آثَمٌ، له عنْدَ اللهِ من الكفَّارَةِ التي أمرَه اللهُ بِها" .
