الطبراني:٨٥٢٥حَدَّثَنَا مُحَمَّدُ بْنُ عَلِيٍّ الصَّائِغُ الْمَكِّيُّ ثنا سَعِيدُ بْنُ مَنْصُورٍ ثنا أَبُو مُعَاوِيَةَ عَنِ الْأَعْمَشِ عَنْ مُجَاهِدٍ عَنْ أَبِي مَعْمَرٍ عَنِ ابْنِ مَسْعُودٍ قَالَ

«لَا يَصْلُحُ مِنَ الْكَذِبِ هَزْلٌ وَلَا جِدٌّ وَلَا أَنْ يَعِدَ أَحَدُكُمْ صَبِيَّهُ شَيْئًا ثُمَّ لَا يُنْجِزَ لَهُ»
