صَحِيحُ مُسْلِمٍ
Sahih Muslim 1651 d
The Book of Oaths
It is recommended for the one who swears an oath then sees that something else is better than it; To do that which is better and offer expiation for his oath
وَحَدَّثَنَا مُحَمَّدُ بْنُ طَرِيفٍ، حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ، عَنِ الشَّيْبَانِيِّ، عَنْ عَبْدِ الْعَزِيزِ، بْنِ رُفَيْعٍ عَنْ تَمِيمٍ الطَّائِيِّ، عَنْ عَدِيِّ بْنِ حَاتِمٍ، أَنَّهُ سَمِعَ النَّبِيَّ صلى الله عليه وسلم يَقُولُ ذَلِكَ .
