Sunan at-Tirmithiy كتاب العلم باب ما جاء فى الأخذ بالسنة واجتناب البدع

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ أَخْبَرَنَا مُحَمَّدُ بْنُ عُيَيْنَةَ عَنْ مَرْوَانَ بْنِ مُعَاوِيَةَ الْفَزَارِىِّ عَنْ كَثِيرِ بْنِ عَبْدِ اللَّهِ عَنْ أَبِيهِ عَنْ جَدِّهِ أَنَّ النَّبِىَّ صلى الله عليه وسلم قَالَ لِبِلاَلِ بْنِ الْحَارِثِ اعْلَمْ. قَالَ مَا أَعْلَمُ يَا رَسُولَ اللَّهِ قَالَ اعْلَمْ يَا بِلاَلُ. قَالَ مَا أَعْلَمُ يَا رَسُولَ اللَّهِ قَالَ أَنَّهُ مَنْ أَحْيَا سُنَّةً مِنْ سُنَّتِى قَدْ أُمِيتَتْ بَعْدِى فَإِنَّ لَهُ مِنَ الأَجْرِ مِثْلَ مَنْ عَمِلَ بِهَا مِنْ غَيْرِ أَنْ يَنْقُصَ مِنْ أُجُورِهِمْ شَيْئًا وَمَنِ ابْتَدَعَ بِدْعَةَ ضَلاَلَةٍ لاَ يَرْضَاهَا اللَّهُ وَرَسُولُهُ كَانَ عَلَيْهِ مِثْلُ آثَامِ مَنْ عَمِلَ بِهَا لاَ يَنْقُصُ ذَلِكَ مِنْ أَوْزَارِ النَّاسِ شَيْئًا. قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ. وَمُحَمَّدُ بْنُ عُيَيْنَةَ هُوَ مِصِّيصِىٌّ شَامِىٌّ وَكَثِيرُ بْنُ عَبْدِ اللَّهِ هُوَ ابْنُ عَمْرِو بْنِ عَوْفٍ الْمُزَنِىُّ.
The Prophet, peace and blessings of God be upon him, said to Bīlal Ibnul-Ḥarith, "Be advised!" He said, "What should I be advised, Messenger of God?" He said, "Be advised, Bīlal!" He said, "What should I be advised, Messenger of God?" He said, "That whoever revives a sunnah (1) of mine that has died after me, will be equally rewarded as whoever acts upon it, without it diminishing anything from their rewards. And whoever introduces an innovation of misguidance that God and His Messenger would not approve of, will equally bare the sins of whoever acts upon it, without it diminishing anything from their sins."
(1) Record of the tradition of prophet Muḥammad, peace and blessings of God be upon him, including his sayings, actions, biography, physical and behavioral depiction, and his approval of something said or done in his presence, as narrated by his companions.
