Sahih al-Bukhari, Hadith 6626 ⓘ

Narrated Abu Huraira: Allah's Messenger said, "Anyone who takes an oath through which his family may be harmed, and insists on keeping it, he surely commits a sin greater (than that of dissolving his oath). He should rather compensate for that oath by making expiation."

حَدَّثَنِي إِسْحَاقُ يَعْنِي ابْنَ إِبْرَاهِيمَ، حَدَّثَنَا يَحْيَى بْنُ صَالِحٍ، حَدَّثَنَا مُعَاوِيَةُ، عَنْ يَحْيَى، عَنْ عِكْرِمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَنِ اسْتَلَجَّ فِي أَهْلِهِ بِيَمِينٍ فَهْوَ أَعْظَمُ إِثْمًا، لِيَبَرَّ ‏" ‏‏.‏ يَعْنِي الْكَفَّارَةَ‏.‏
