"Make atonement for your oath and then do the thing that is better." Abu Dawud said: The version of this tradition transmitted by Abu Musa al-Ash'ari, 'Adi b. Hatim and Abu Hurairah are variant. Some of them indicate breaking the oath before making atonement, and other making atonement before breaking the oath.  

أبو داود:٣٢٧٨ – حَدَّثَنَا يَحْيَى بْنُ خَلَفٍ حَدَّثَنَا عَبْدُ الأَعْلَى حَدَّثَنَا سَعِيدٌ عَنْ قَتَادَةَ عَنِ الْحَسَنِ عَنْ عَبْدِ الرَّحْمَنِ بْنِ سَمُرَةَ نَحْوَهُ قَالَ فَكَفِّرْ

عَنْ يَمِينِكَ ثُمَّ ائْتِ الَّذِي هُوَ خَيْرٌ  

قَالَ أَبُو دَاوُدَ أَحَادِيثُ أَبِي مُوسَى الأَشْعَرِيِّ وَعَدِيِّ بْنِ حَاتِمٍ وَأَبِي هُرَيْرَةَ فِي هَذَا الْحَدِيثِ رُوِيَ عَنْ كُلِّ وَاحِدٍ مِنْهُمْ فِي بَعْضِ الرِّوَايَةِ الْحِنْثُ قَبْلَ الْكَفَّارَةِ وَفِي بَعْضِ الرِّوَايَةِ الْكَفَّارَةُ قَبْلَ الْحِنْثِ
