الطبراني:٤٤٣٣حَدَّثَنَا عَبْدَانُ بْنُ أَحْمَدَ ثنا الْحَسَنُ بْنُ جُمْهُورٍ ثنا مُحَمَّدُ بْنُ عُمَرَ الْوَاقِدِيُّ ثنا عَبْدُ اللهِ بْنُ نُوحٍ عَنْ مُحَمَّدِ بْنِ سَهْلِ بْنِ أَبِي حَثْمَةَ عَنْ رَافِعِ بْنِ خَدِيجٍ قَالَ

«قَدِمَتْ عَلَى رَسُولِ اللهِ ﷺ وُفُودُ الْعَرَبِ فَلَمْ يَقْدَمْ عَلَيْنَا وَفْدٌ أَقْسَى قُلُوبًا وَلَا أَحْرَى أَنْ يَكُونَ الْإِسْلَامُ لَمْ يَقَرَّ فِي قُلُوبِهِمْ مِنْ بَنِي حَنِيفَةَ»
