حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُنِيرٍ، سَمِعَ أَبَا النَّضْرِ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللَّهِ ـ يَعْنِي ابْنَ دِينَارٍ ـ عَنْ أَبِيهِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِنَّ الْعَبْدَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ رِضْوَانِ اللَّهِ لاَ يُلْقِي لَهَا بَالاً، يَرْفَعُ اللَّهُ بِهَا دَرَجَاتٍ، وَإِنَّ الْعَبْدَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ سَخَطِ اللَّهِ لاَ يُلْقِي لَهَا بَالاً يَهْوِي بِهَا فِي جَهَنَّمَ ".
