Hadith 96
قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " لأَنْ يَلَجَّ أَحَدُكُمْ بِيَمِينِهِ فِي أَهْلِهِ، آثَمُ لَهُ عِنْدَ اللَّهِ مِنْ أَنْ يُعْطِيَ كَفَّارَتَهُ الَّتِي فَرَضَ اللَّهُ عَزَّ وَجَلَّ "
And the Messenger of Allah, peace and blessings be upon him, said: "By Allah! For any one of you to persist in severing ties with his family due to an oath is a greater sin in the sight of Allah than (breaking the oath and) offering the expiation which Allah has made obligatory upon him."
