Hadith 15

Sahih Muslim

Book 27: The Book of Oaths

Chapter 3

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

باب نَدْبِ مَنْ حَلَفَ يَمِينًا فَرَأَى غَيْرَهَا خَيْرًا مِنْهَا أَنْ يَأْتِيَ الَّذِي هُوَ خَيْرٌ وَيُكَفِّرَ عَنْ يَمِينِهِ

Sahih Muslim 1649f
وَحَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا الصَّعْقُ، - يَعْنِي ابْنَ حَزْنٍ - حَدَّثَنَا مَطَرٌ الْوَرَّاقُ، حَدَّثَنَا زَهْدَمٌ الْجَرْمِيُّ، قَالَ دَخَلْتُ عَلَى أَبِي مُوسَى وَهُوَ يَأْكُلُ لَحْمَ دَجَاجٍ وَسَاقَ الْحَدِيثَ بِنَحْوِ حَدِيثِهِمْ وَزَادَ فِيهِ قَالَ ‏ ‏ ‏.‏
"‏ إِنِّي وَاللَّهِ مَا نَسِيتُهَا ‏"
Zahdam al-Jarmi reported:

I visited Abu Musa and lie was eating fowl's meat. The rest of the hadith is the same with this addition that he (the Holy Prophet) said: By Allah, I did not forget it.
