" He should expiate for (breaking) the vow and do that which is better."  

مسلم:١٦٥٠dوَحَدَّثَنِي الْقَاسِمُ بْنُ زَكَرِيَّاءَ حَدَّثَنَا خَالِدُ بْنُ مَخْلَدٍ حَدَّثَنِي سُلَيْمَانُ يَعْنِي ابْنَ بِلاَلٍ

حَدَّثَنِي سُهَيْلٌ فِي هَذَا الإِسْنَادِ بِمَعْنَى حَدِيثِ مَالِكٍ فَلْيُكَفِّرْ يَمِينَهُ وَلْيَفْعَلِ الَّذِي هُوَ خَيْرٌ
