Ghudaif b. al-Harith ath-Thumali reported God’s messenger as saying, “No people introduce an innovation without its equivalent being withdrawn from the sunna; so holding firmly to a sunna is better than introducing an innovation.” Ahmad transmitted it.

وَعَن غُضَيْف بن الْحَارِث الثمالِي قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: (مَا أَحْدَثَ قَوْمٌ بِدْعَةً إِلَّا رُفِعَ مِثْلُهَا مِنَ السُّنَّةِ فَتَمَسُّكٌ بِسُنَّةٍ خَيْرٌ مِنْ إِحْدَاث بِدعَة) رَوَاهُ أَحْمد
