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