6) باب مَنْ سَنَّ سُنَّةً حَسَنَةً أَوْ سَيِّئَةً وَمَنْ دَعَا إِلَى هُدًى أَوْ ضَلاَلَةٍ

حَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، وَقُتَيْبَةُ بْنُ سَعِيدٍ، وَابْنُ، حُجْرٍ قَالُوا حَدَّثَنَا إِسْمَاعِيلُ، - يَعْنُونَ ابْنَ جَعْفَرٍ - عَنِ الْعَلاَءِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏‏ ‏.‏ "‏ مَنْ دَعَا إِلَى هُدًى كَانَ لَهُ مِنَ الأَجْرِ مِثْلُ أُجُورِ مَنْ تَبِعَهُ لاَ يَنْقُصُ ذَلِكَ مِنْ أُجُورِهِمْ شَيْئًا وَمَنْ دَعَا إِلَى ضَلاَلَةٍ كَانَ عَلَيْهِ مِنَ الإِثْمِ مِثْلُ آثَامِ مَنْ تَبِعَهُ لاَ يَنْقُصُ ذَلِكَ مِنْ آثَامِهِمْ شَيْئًا ‏"
