"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, "Allah does not accept the prayer of any one of you if he is in a state of impurity until he performs ablution."  

قَالَ رَسُولُ اللهِ ﷺ لَا يَقْبَلُ اللهُ صَلَاةَ أَحَدِكِمْ إِذَا أَحْدَثَ حَتَّى يَتَوَضَّأَ  

"وَاللهِ لأَنْ يَلَجَّ أَحَدُكُمْ بِيَمِينِهِ فِي أَهْلِهِ آثَم لَهُ عِنْدَ اللهِ مِنْ أَنْ يُعْطِي كَفارَتَهُ الَّتِي افتَرَضَ اللهُ عَلَيهِ".
