أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ عَنْ عَبْدِ الرَّحْمَنِ قَالَ حَدَّثَنَا مَهْدِيُّ بْنُ مَيْمُونٍ قَالَ أَخْبَرَنِي مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ أَبِي يَعْقُوبَ قَالَ أَخْبَرَنِي رَجَاءُ بْنُ حَيْوَةَ عَنْ أَبِي أُمَامَةَ قَالَ أَتَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقُلْتُ مُرْنِي بِأَمْرٍ آخُذُهُ عَنْكَ قَالَ عَلَيْكَ بِالصَّوْمِ فَإِنَّهُ لَا مِثْلَ لَهُ
