"The Messenger of Allah said: 'Whoever introduces a good practice that is followed, he will receive its reward and a reward equivalent to that of those who follow it, without that detracting from their reward in their slightest. And whoever introduces a bad practice that is followed, he will receive its sin and a burden of sin equivalent to that of those who follow it, without that detracting from their burden in the slightest.'"  

قَالَ رَسُولُ اللَّهِ ﷺ 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  

"The Messenger of Allah said: 'Whoever introduces a good practice that is followed after him, will have a reward for that and the equivalent of their reward, without that detracting from their reward in the slightest. Whoever introduces an evil practice that is followed after him, will bear the burden of sin for that and the equivalent of their burden of sin, without that detracting from their burden in the slightest.'"  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ سَنَّ سُنَّةً حَسَنَةً فَعُمِلَ بِهَا بَعْدَهُ كَانَ لَهُ أَجْرُهَا وَمِثْلُ أُجُورِهِمْ مِنْ غَيْرِ أَنْ يَنْقُصَ مِنْ أُجُورِهِمْ شَيْئًا وَمَنْ سَنَّ سُنَّةً سَيِّئَةً فَعُمِلَ بِهَا بَعْدَهُ كَانَ عَلَيْهِ وِزْرُهُ وَمِثْلُ أَوْزَارِهِمْ مِنْ غَيْرِ أَنْ يَنْقُصَ مِنْ أَوْزَارِهِمْ شَيْئًا  

"The Messenger of Allah said: 'Whoever introduces a good practice that is followed after him, will have a reward for that and the equivalent of their reward, without that detracting from their reward in the slightest. Whoever introduces an evil practice that is followed after him, will bear the burden of sin for that and the equivalent of their burden of sin, without that detracting from their burden in the slightest.'" (Using translation from Ibn Mājah 207)   

قَالَ رَسُولُ اللهِ ﷺ مَنْ سَنَّ سُنَّةَ ضَلَالٍ فَاتُّبِعَ عَلَيْهَا كَانَ عَلَيْهِ مِثْلُ أَوْزَارِهِمْ مِنْ غَيْرِ أَنْ يَنْقُصَ مِنْ أَوْزَارِهِمْ شَيْءٌ وَمَنْ سَنَّ سُنَّةَ هُدًى فَاتُّبِعَ عَلَيْهَا كَانَ لَهُ مِثْلُ أُجُورِهِمْ مِنْ غَيْرِ أَنْ يَنْقُصَ مِنْ أُجُورِهِمْ شَيْءٌ  

[Machine] A man asked during the time of the Prophet ﷺ, so the people held back. Then, a man gave him something, so he gave it to the people. The Prophet ﷺ said, "Whoever starts a good practice, he will have its reward and the reward of those who follow him, without their rewards being decreased in any way. And whoever starts an evil practice, he will bear its burden and the burden of those who follow him, without their burdens being decreased in any way."  

سَأَلَ رَجُلٌ عَلَى عَهْدِ النَّبِيِّ ﷺ فَأَمْسَكَ الْقَوْمُ ثُمَّ إِنَّ رَجُلًا أَعْطَاهُ فَأَعْطَى الْقَوْمُ فَقَالَ النَّبِيُّ ﷺ مَنْ سَنَّ خَيْرًا فَاسْتُنَّ بِهِ كَانَ لَهُ أَجْرُهُ وَمِنْ أُجُورِ مَنْ يَتَّبِعُهُ غَيْرَ مُنْتَقِصٍ مِنْ أُجُورِهِمْ شَيْئًا وَمَنْ سَنَّ شَرًّا فَاسْتُنَّ بِهِ كَانَ عَلَيْهِ وِزْرُهُ وَمِنْ أَوْزَارِ مَنْ يَتَّبِعُهُ غَيْرَ مُنْتَقِصٍ مِنْ أَوْزَارِهِمْ شَيْئًا  

"مَنْ سَنَّ في الإِسْلامِ خَيرًا فَاسْتُنَّ بهِ كَانَ لَهُ أَجْرُهُ وَمِثْلُ أُجُورِ مَنْ تَبعَه من غير أَنْ يَنْقُصَ مِن أُجُورهم شَيئًا، ومَن سَنَّ شَرّا (*) فَاسْتُنَّ بِهِ كَانَ عَلَيهِ وزْرُه وَمِثْلُ أَوْزَار مَن تَبعَه مِن غَير أَنْ يَنْقُصَ مِن أَوْزَارهم شَيئًا".  

"مَنْ سَنَّ سُنَّةً حَسَنَةً عُمِلَ بها بَعْدَهُ كَانَ لَه أَجْرُهُ وَمِثْلُ أُجُورِهم مِنْ غَيرِ أَن يَنْتَقِصَ مِنْ أُجُورِهِمْ شَيئًا، وَمَنْ سَنَ سُنَّةً سيِّئَةً فَعُمِلَ بِهَا بَعْدَهُ كَانَ عَلَيهِ وزْرُهَا وَمِثَلُ أَوْزَارِهمْ مِنْ غَيرِ أَنْ يَنْتَقِصَ مِنْ أَوْزَارِهِمْ شَيئًا".  

"مَنْ سَنَّ سُنَّةَ هُدًى فَاتُّبِعَ عَلَيهَا كَانَ لَهُ أَجْرُهَا وَأَجْرُ مَنْ عَمِلَ بهَا مِنْ غَيرِ أَنْ يَنْقُصَ مِنْ أُجُورِهم شَيئًا، ومن سَنَّ سُنَّةَ ضَلالةٍ فَاتُّبِعَ عَلَيهَا كَانَ عَلَيهِ مِثْلُ أَوزَارِهم مِن غَيرِ أَنْ يَنْقُصَ مِن أَوْزَارِهم شَيئًا".
