He who introduced some good practice in Islam which was followed after him (by people) he would be assured of reward like one who followed it, without their rewards being diminished in any respect. And he who introduced some evil practice in Islam which had been followed subsequently (by others), he would be required to bear the burden like that of one who followed this (evil practice) without their's being diminished in any respect.  

جَاءَ نَاسٌ مِنَ الأَعْرَابِ إِلَى رَسُولِ اللَّهِ ﷺ عَلَيْهِمُ الصُّوفُ فَرَأَى سُوءَ حَالِهِمْ قَدْ أَصَابَتْهُمْ حَاجَةٌ فَحَثَّ النَّاسَ عَلَى الصَّدَقَةِ فَأَبْطَئُوا عَنْهُ حَتَّى رُئِيَ ذَلِكَ فِي وَجْهِهِ قَالَ ثُمَّ إِنَّ رَجُلاً مِنَ الأَنْصَارِ جَاءَ بِصُرَّةٍ مِنْ وَرِقٍ ثُمَّ جَاءَ آخَرُ ثُمَّ تَتَابَعُوا حَتَّى عُرِفَ السُّرُورُ فِي وَجْهِهِ فَقَالَ رَسُولُ اللَّهِ ﷺ مَنْ سَنَّ فِي الإِسْلاَمِ سُنَّةً حَسَنَةً فَعُمِلَ بِهَا بَعْدَهُ كُتِبَ لَهُ مِثْلُ أَجْرِ مَنْ عَمِلَ بِهَا وَلاَ يَنْقُصُ مِنْ أُجُورِهِمْ شَىْءٌ وَمَنْ سَنَّ فِي الإِسْلاَمِ سُنَّةً سَيِّئَةً فَعُمِلَ بِهَا بَعْدَهُ كُتِبَ عَلَيْهِ مِثْلُ وِزْرِ مَنْ عَمِلَ بِهَا وَلاَ يَنْقُصُ مِنْ أَوْزَارِهِمْ شَىْءٌ  

[Machine] A man from the Ansar came to the Prophet ﷺ with a handful of gold and said, "This is for the sake of Allah." Then Abu Bakr stood up and gave, and then Umar stood up and gave, and then the Muhajirun stood up and gave. And the face of the Messenger of Allah ﷺ brightened until I saw the radiance in his cheeks. Then he said, "Whoever starts a good practice in Islam and others act upon it, he will receive the reward of those who act upon it without their reward being diminished in any way. And whoever starts an evil practice in Islam and others act upon it, he will bear the burden of their sins without their sins being diminished in any way."  

أَنَّ رَجُلًا مِنَ الْأَنْصَارِ جَاءَ إِلَى النَّبِيِّ ﷺ بِصُرَّةٍ مِنْ ذَهَبٍ تَمْلَأُ مَا بَيْنَ أَصَابِعِهِ فَقَالَ هَذِهِ فِي سَبِيلِ اللهِ ﷻ ثُمَّ قَامَ أَبُو بَكْرٍ فَأَعْطَوْا فَأَعْطَى ثُمَّ قَامَ عُمَرُ فَأَعْطَى ثُمَّ قَامَ الْمُهَاجِرُونَ فَأَعْطَوْا قَالَ فَأَشْرَقَ وَجْهُ رَسُولِ اللهِ ﷺ حَتَّى رَأَيْتُ الْإِشْرَاقَ فِي وَجْنَتَيْهِ ثُمَّ قَالَ مَنْ سَنَّ سُنَّةً صَالِحَةً فِي الْإِسْلَامِ فَعُمِلَ بِهَا بَعْدَهُ كَانَ لَهُ مِثْلُ أُجُورِهِمْ مِنْ غَيْرِ أَنْ يُنْتَقَصَ مِنْ أُجُورِهِمْ شَيْءٌ وَمَنْ سَنَّ فِي الْإِسْلَامِ سُنَّةً سَيِّئَةً فَعُمِلَ بِهَا بَعْدَهُ كَانَ عَلَيْهِ مِثْلُ أَوْزَارِهِمْ مِنْ غَيْرِ أَنْ يُنْتَقَصَ مِنْ أَوْزَارِهِمْشَيْءٌ  

[Machine] A group of people from the Bedouin Arab tribe came to the Prophet Muhammad ﷺ while they were seeking the spoils of war. So the Messenger of Allah ﷺ urged the people to give charity, but they hesitated until it could be seen on his face. Then a man from the Ansar (helpers of the Prophet) brought a piece of silver and threw it, and the people followed suit until it was known on his face. The Prophet ﷺ said, "Whoever starts a good practice and is followed by others, will receive the reward of it and the equivalent reward of those who follow it, without any decrease in their own rewards. And whoever starts an evil practice and is followed by others, will carry the burden of it and the burden of those who follow it, without any decrease in their own burdens."  

أَنَّ قَوْمًا أَتَوْا النَّبِيَّ ﷺ مِنَ الْأَعْرَابِ مُجْتَابِي النِّمَارِ فَحَثَّ رَسُولُ اللهِ ﷺ النَّاسَ عَلَى الصَّدَقَةِ فَأَبْطَئُوا حَتَّى رُئِيَ ذَلِكَ فِي وَجْهِهِ فَجَاءَ رَجُلٌ مِنَ الْأَنْصَارِ بِقِطْعَةِ تِبْرٍ فَطَرَحَهَا فَتَتَابَعَ النَّاسُ حَتَّى عُرِفَ ذَلِكَ فِي وَجْهِهِ فَقَالَ مَنْ سَنَّ سُنَّةً حَسَنَةً فَعُمِلَ بِهَا مِنْ بَعْدِهِ كَانَ لَهُ أَجْرُهَا وَمِثْلُ أَجْرِ مَنْ عَمِلَ بِهَا مِنْ غَيْرِ أَنْ يُنْتَقَصَ مِنْ أُجُورِهِمْ شَيْءٌ وَمَنْ سَنَّ سُنَّةً سَيِّئَةً عُمِلَ بِهَا مِنْ بَعْدِهِ كَانَ عَلَيْهِ وِزْرُهَا وَوِزْرُ مَنْ عَمِلَ بِهَا وَلَا يُنْقِصُ ذَلِكَ مِنْ أَوْزَارِهِمْ شَيْئًا  

[Machine] The Messenger of Allah ﷺ addressed us and urged us to give charity. The people seemed reluctant, until anger was seen on his face. He said it a few more times, until a man from the Ansar came with a pile of goods and gave it as charity. Then people followed suit and started giving until happiness was seen on his face. He said, "Whoever starts a good tradition will have its reward and the reward of those who do it, without any decrease in their rewards. And whoever starts an evil tradition, will bear its burden and the burden of those who do it, without any decrease in their burdens." He said this, referring to Abu Mu'awiyah, without decreasing their burdens.  

خَطَبَنَا رَسُولُ اللهِ ﷺ فَحَثَّنَا عَلَى الصَّدَقَةِ فَأَبْطَأَ النَّاسُ حَتَّى رُئِيَ فِي وَجْهِهِ الْغَضَبُ وَقَالَ مَرَّةً حَتَّى بَانَ ثُمَّ إِنَّ رَجُلًا مِنَ الْأَنْصَارِ جَاءَ بِصُرَّةٍ فَأَعْطَاهَاإِيَّاهُ ثُمَّ تَتَابَعَ النَّاسُ فَأَعْطَوْا حَتَّى رُئِيَ فِي وَجْهِهِ السُّرُورُ فَقَالَ مَنْ سَنَّ سُنَّةً حَسَنَةً كَانَ لَهُ أَجْرُهَا وَمِثْلُ أَجْرِ مَنْ عَمِلَ بِهَا مِنْ غَيْرِ أَنْ يُنْتَقَصَ مِنْ أُجُورِهِمْ شَيْءٌ وَمَنْ سَنَّ سُنَّةً سَيِّئَةً كَانَ عَلَيْهِ وِزْرُهَا وَمِثْلُ وِزْرِ مَنْ عَمِلَ بِهَا مِنْ غَيْرِ أَنْ يُنْتَقَصَ مِنْ أَوْزَارِهِمْ شَيْءٌ قَالَ مَرَّةً يَعْنِي أَبَا مُعَاوِيَةَ مِنْ غَيْرِ أَنْ يَنْقُصَ  

[Machine] The Messenger of Allah ﷺ delivered a sermon and exhorted the people to give charity. They were slow to respond until anger became apparent on his face. Then, a man from the Ansar came with a bag filled with items, and the people began to follow suit until it was seen on his face that he was delighted. He said, "Whoever starts a good practice will receive its reward and the reward of those who follow it, without reducing anything from their rewards. And whoever initiates an evil practice shall carry its burden and the burden of those who act upon it, without diminishing anything from their burdens."  

خَطَبَنَا رَسُولُ اللَّهِ ﷺ فَحَثَّ النَّاسَ عَلَى الصَّدَقَةِ فَأَبْطَئُوا حَتَّى بَانَ فِي وَجْهِهِ الْغَضَبُ ثُمَّ إِنَّ رَجُلًا مِنَ الْأَنْصَارِ جَاءَ بِصُرَّةٍ فَتَتَابَعَ النَّاسُ حَتَّى رُئِيَ فِي وَجْهِهِ السُّرُورُ فَقَالَ «مَنْ سَنَّ سُنَّةً حَسَنَةً كَانَ لَهُ أَجْرُهُ وَمِثْلُ أَجْرِ مَنْ عَمِلَ بِهَا مِنْ غَيْرِ أَنْ يُنْقَصَ مِنْ أُجُورِهِمْ شَيْءٌ وَمَنْ سَنَّ سُنَّةً سَيِّئَةً كَانَ عَلَيْهِ وِزْرُهُ وَمِثْلُ وِزْرِ مَنْ عَمِلَ بِهَا مِنْ غَيْرِ أَنْ يُنْقَصَ مِنْ أَوْزَارِهِمْ شَيْءٌ»  

[Machine] A group of people from the desert came to the Prophet ﷺ seeking advice. The Prophet ﷺ encouraged people to give charity, but they hesitated until it was evident on the face of the Messenger of Allah ﷺ. Then, a man from the Ansar came with a piece of gold, and he threw it. People started following one another in giving charity until joy became apparent on the face of the Messenger of Allah ﷺ. He said, "Whoever starts a good tradition that is followed, then he will have a reward similar to those who follow it, without their rewards being diminished. And whoever starts an evil tradition that is followed, then he will bear the burden of sin and the burden of those who follow it, without their burdens being diminished."  

جَاءَ قَوْمٌ مِنْ أَهْلِ الْبَادِيَةِ إِلَى النَّبِيِّ ﷺ مُجْتَابِي النِّمَارِ فَسَأَلُوهُ فَحَثَّ النَّبِيُّ ﷺ النَّاسَ عَلَى الصَّدَقَةِ فَأَبْطَئُوا بِهَا حَتَّى عُرِفَ ذَلِكَ فِي وَجْهِ رَسُولِ اللهِ ﷺ فَجَاءَ رَجُلٌ مِنَ الْأَنْصَارِ بِقِطْعَةِ تِبْرٍ فَأَلْقَاهَا فَتَتَابَعَ النَّاسُ فِي الصَّدَقَةِ حَتَّى عُرِفَ السُّرُورُ فِي وَجْهِ رَسُولِ اللهِ ﷺ وَقَالَ «مَنْ سَنَّ سُنَّةً حَسَنَةً فَعُمِلَ بِهَا بَعْدَهُ كَانَ لَهُ مِثْلُ أَجْرِهَا وَأَجْرِ مَنْ عَمِلَ بِهَا مِنْ غَيْرِ أَنْ يَنْقُصَ مِنْ أُجُورِهِمْ شَيْءٌ وَمَنْ سَنَّ سُنَّةً سَيِّئَةً فَعُمِلَ بِهَا كَانَ عَلَيْهِ وِزْرُهَا وَوِزْرُ مَنْ عَمِلَ بِهَا مِنْ غَيْرِ أَنْ يَنْقُصَ مِنْ أَوْزَارِهِمْ شَيْءٌ»  

[Machine] A man asked the Messenger of Allah ﷺ to encourage people to give charity until it could be seen in his face. Then a man from the Ansar came with a gift and presented it to the Prophet ﷺ. The joy could be seen in the face of the Messenger of Allah ﷺ. He said, "Whoever establishes a good practice in Islam and someone practices it after him, both receive a reward for it and the reward of everyone who acts upon it does not diminish in any way. And whoever establishes a bad practice in Islam and someone practices it after him, carries the burden of both and the burden of everyone who acts upon it does not diminish in any way."  

سَأَلَ رَجُلٌ رَسُولَ اللهِ ﷺ فَحَثَّ النَّاسَ عَلَى الصَّدَقَةِ حَتَّى رُؤِيَ ذَلِكَ فِي وَجْهِ رَسُولِ اللهِ ﷺ فَجَاءَ رَجُلٌ مِنَ الْأَنْصَارِ بِذَهَبَةٍ فَنَبَذَهَا إِلَى النَّبِيِّ ﷺ فَرُؤِيَ السُّرُورُ فِي وَجْهِ رَسُولِ اللهِ ﷺ فَقَالَ «مَنْ سَنَّ سُنَّةً حَسَنَةً فِي الْإِسْلَامِ فَعُمِلَ بِهَا مِنْ بَعْدِهِ كَانَ لَهُ أَجْرُهَا وَمَثَلُ أَجْرِ مَنْ عَمِلَ بِهَا لَا يَنْقُصُ مِنْ أُجُورِهِمْ شَيْءٌ وَمَنْ سَنَّ سُنَّةً سَيِّئَةً فِي الْإِسْلَامِ فَعُمِلَ بِهَا بَعْدَهُ كَانَ عَلَيْهِ وِزْرُهَا وَمَثَلُ وِزْرِ مَنْ عَمِلَ بِهَا لَا يَنْقُصُ مِنْ أَوْزَارِهِمْ شَيْءٌ»  

[Machine] A man from the Ansar came to the Prophet ﷺ with a purse made of gold that was filled between his fingers. He said, "This is for the sake of Allah." Then Abu Bakr got up and gave to him, then Umar got up and gave to him. Then the Mujahideen and the Ansar got up and gave to him until the face of the Messenger of Allah ﷺ shone, and we saw the radiance on his cheek. Then the Prophet ﷺ said, "Whoever starts a good Sunnah in Islam and it is followed after him, he will have the reward of those who follow it, without their rewards being diminished in any way. And whoever starts an evil Sunnah in Islam and it is followed after him, he will bear the burden of it and the burden of those who follow it, without their burdens being diminished in any way."  

أَنَّ رَجُلًا مِنَ الْأَنْصَارِ جَاءَ النَّبِيَّ ﷺ بِصُرَّةٍ مِنْ ذَهَبٍ يَمْلَأُ مَا بَيْنَ أَصَابِعِهِ فَقَالَ هَذِهِ فِي سَبِيلِ اللهِ ثُمَّ قَامَ أَبُو بَكْرٍ ؓ فَأَعْطَاهُ ثُمَّ قَامَ عُمَرُ ؓ فَأَعْطَاهُ ثُمَّ قَامَ الْمُهَاجِرُونَ وَالْأَنْصَارُ فَأَعْطَوْا فَأَشْرَقَ وَجْهُ رَسُولِ اللهِ ﷺ حَتَّى رَأَيْنَا الْإِشْرَاقَ فِي وَجْنَتِهِ ثُمَّ قَالَ النَّبِيُّ ﷺ «مَنِ اسْتَنَّ سُنَّةً صَالِحَةً فِي الْإِسْلَامِ فَعُمِلَ بِهَا بَعْدَهُ كَانَ لَهُ مِثْلُ أُجُورِهِمْ مِنْ غَيْرِ أَنْ يَنْقُصَ مِنْ أُجُورِهِمْ شَيْءٌ وَمَنْ سَنَّ فِي الْإِسْلَامِ سُنَّةً سَيِّئَةً فَعُمِلَ بِهَا بَعْدَهُ كَانَ عَلَيْهِ مِثْلُ أَوْزَارِهِمْ مِنْ غَيْرِ أَنْ يَنْقُصَ مِنْ أَوْزَارِهِمْ شَيْءٌ»
