حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الْمَلِكِ بْنِ أَبِي الشَّوَارِبِ، حَدَّثَنَا أَبُو عَوَانَةَ، حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ عُمَيْرٍ، عَنِ الْمُنْذِرِ بْنِ جَرِيرٍ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَنْ سَنَّ سُنَّةً حَسَنَةً فَعُمِلَ بِهَا كَانَ لَهُ أَجْرُهَا وَمِثْلُ أَجْرِ مَنْ عَمِلَ بِهَا لاَ يَنْقُصُ مِنْ أُجُورِهِمْ شَيْئًا وَمَنْ سَنَّ سُنَّةً سَيِّئَةً فَعُمِلَ بِهَا كَانَ عَلَيْهِ وِزْرُهَا وَوِزْرُ مَنْ عَمِلَ بِهَا مِنْ بَعْدِهِ لاَ يَنْقُصُ مِنْ أَوْزَارِهِمْ شَيْئًا " .
Muhammad ibn Abd al-Malik ibn Abi al-Shawarib reported to us: Abu Awanah reported to us: Abd al-Malik ibn Umayr reported to us, from al-Mundhir ibn Jarir, from his father, who said: The Messenger of Allah (Allah bless him and grant him peace) said, ‘Whoever establishes a good practice that is followed will have its reward and the like of the reward of those who follow it, without their rewards being diminished at all. Whoever establishes a bad practice that is followed will bear its burden and the like of the burden of those who follow it, without their burdens being diminished at all.’
