وَعَنْ بِلَالِ بْنِ الْحَارِثِ الْمُزَنِيِّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسلم: «من أَحْيَا سُنَّةً مِنْ سُنَّتِي قَدْ أُمِيتَتْ بَعْدِي فَإِنَّ لَهُ مِنَ الْأَجْرِ مِثْلَ أُجُورِ مَنْ عَمِلَ بِهَا مِنْ غَيْرِ أَنْ يَنْقُصَ مِنْ أُجُورِهِمْ شَيْئًا وَمَنِ ابْتَدَعَ بِدْعَةً ضَلَالَةً لَا يَرْضَاهَا اللَّهُ وَرَسُولُهُ كَانَ عَلَيْهِ مِنَ الْإِثْمِ مِثْلُ آثَامِ مَنْ عَمِلَ بِهَا لَا يَنْقُصُ من أوزارهم شَيْئا» . رَوَاهُ التِّرْمِذِيّ وَرَوَاهُ ابْنُ مَاجَهْ عَنْ كَثِيرِ بْنِ عَبْدِ اللَّهِ بْنِ عَمْرٍو عَنْ أَبِيهِ عَنْ جَدِّهِ

Bilal b. Harith al-Muzani reported God’s messenger as saying, “Whoever revives a sunna of mine which has been neglected after my time will have a reward equal to the rewards of those who act upon it, without their rewards being diminished in any way. But whoever invents a misleading innovation with which God and His messenger are not pleased will be charged with a sin equal to the sins of those who act upon it without that diminishing their loads in any way.” Tirmidhi transmitted it, and Ibn Majah transmitted it from Kathir b. ‘Abdallah b. ‘Amr from his father from his grandfather.
