Arabic hadith text
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 ".
Translation
The Messenger of Allah, peace and blessings be upon him, said: ‘By Allah, for one of you to persist in an oath against his family is more sinful before Allah than giving the expiation Allah has made obligatory upon him.’
