حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ حَدَّثَنَا لَيْثُ بْنُ سَعِيدٍ عَنِ ابْنِ الْهَادِ عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ بْنِ الْحَارِثِ عَنْ عَامِرِ بْنِ سَعْدٍ عَنِ الْعَبَّاسِ بْنِ عَبْدِ الْمُطَّلِبِ أَنَّهُ سَمِعَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ ذَاقَ طَعْمَ الْإِيمَانِ مَنْ رَضِيَ بِاللَّهِ رَبًّا وَبِالْإِسْلَامِ دِينًا وَبِمُحَمَّدٍ نَبِيًّا.
