Sahih Muslim 1650b
Abu Huraira reported Messenger of Allah ﷺ as saying: He who took an oath and then found another thing better than (this) should expiate for the oath (broken) by him and do (the better thing).
وَحَدَّثَنِي أَبُو الطَّاهِرِ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، أَخْبَرَنِي مَالِكٌ، عَنْ سُهَيْلِ بْنِ أَبِي، صَالِحٍ عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ
" مَنْ حَلَفَ عَلَى يَمِينٍ فَرَأَى غَيْرَهَا خَيْرًا مِنْهَا فَلْيُكَفِّرْ عَنْ يَمِينِهِ وَلْيَفْعَلْ " .
