That the Prophet ﷺ said: "Whoever takes an oath, and then he sees that something else is better than it, then he should make atonement for his oath and then do it."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ حَلَفَ عَلَى يَمِينٍ فَرَأَى غَيْرَهَا خَيْرًا مِنْهَا فَلْيُكَفِّرْ عَنْ يَمِينِهِ وَلْيَفْعَلْ قَالَ وَفِي الْبَابِ عَنْ أُمِّ سَلَمَةَ
