صَحِيحُ الْبُخَارِيِّ
Sahih al-Bukhari 6625
Oaths and Vows
"Allah will not punish you for what is unintentional in your oaths, but He will punish you for your deliberate oaths ..."
فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَاللَّهِ لأَنْ يَلِجَّ أَحَدُكُمْ بِيَمِينِهِ فِي أَهْلِهِ آثَمُ لَهُ عِنْدَ اللَّهِ مِنْ أَنْ يُعْطِيَ كَفَّارَتَهُ الَّتِي افْتَرَضَ اللَّهُ عَلَيْهِ .
Allah's Messenger (ﷺ) 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."
