وَقَالَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ وَاللَّهِ لَأَنْ يَلِجَّ أَحَدُکُمْ بِيَمِينِهِ فِي أَهْلِهِ آثَمُ لَهُ عِنْدَ اللَّهِ مِنْ أَنْ يُعْطِيَ کَفَّارَتَهُ الَّتِي افْتَرَضَ اللَّهُ عَلَيْهِ
صحیح بخاری · Hadith 6625
Allah's Apostle also said: "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."
