Sahih Muslim
وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنِ ابْنِ جُرَيْجٍ، ح وَحَدَّثَنِي مُحَمَّدُ، بْنُ رَافِعٍ حَدَّثَنَا ابْنُ أَبِي فُدَيْكٍ، أَخْبَرَنَا الضَّحَّاكُ، - يَعْنِي ابْنَ عُثْمَانَ - كِلاَهُمَا عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم بِمِثْلِ حَدِيثِ اللَّيْثِ .
