Arabic hadith text
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
Translation
Ghuḍayf ibn al-Ḥārith al-Thumālī reported that the Messenger of God said: ‘Whenever a people introduce an innovation, an equivalent measure of the Sunnah is lifted away. Holding fast to a Sunnah is better than introducing an innovation.’ Aḥmad transmitted it.
