حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ مُصْعَبٍ، عَنِ الأَوْزَاعِيِّ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ هِلاَلِ بْنِ أَبِي مَيْمُونَةَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ رِفَاعَةَ الْجُهَنِيِّ، قَالَ كَانَ النَّبِيُّ ـ صلى الله عليه وسلم ـ إِذَا حَلَفَ قَالَ ‏ "‏ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ ‏"‏ ‏.‏
