Sahih Muslim 1650dBook 27, Hadith 21

وَحَدَّثَنِي 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 ‏"‏ ‏.‏

This hadith is narrated on the authority of Suhail with the same chain of transmitters (with these words):
