ابن ماجة:٢٠٩١حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ مُحَمَّدٍ الصَّنْعَانِيُّ حَدَّثَنَا الأَوْزَاعِيُّ عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ عَنْ هِلاَلِ بْنِ أَبِي مَيْمُونَةَ عَنْ عَطَاءِ بْنِ يَسَارٍ عَنْ رِفَاعَةَ بْنِ عَرَابَةَ الْجُهَنِيِّ قَالَ

كَانَتْ يَمِينُ رَسُولِ اللَّهِ ﷺ التَّى يَحْلِفُ بِهَا أَشْهَدُ عِنْدَ اللَّهِ وَالَّذِي نَفْسِي بِيَدِهِ
