“I said to my father: ‘O my father! You prayed behind the Messenger of Allah ﷺ and behind Abu Bakr, ‘Umar and ‘Uthman, and behind ‘Ali here in Kufah for about five years. Did they recite Qunut in Fajr?’ He said: ‘O my son! That is an innovation.’” (Using translation from Ibn Mājah 1241)
«صَلَّيْتُ خَلْفَ رَسُولِ اللهِ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ وَعُثْمَانَ ؓ وَعَلِيٌّ هَاهُنَا بِالْكُوفَةِ نَحْوًا مِنْ خَمْسِ سِنِينَ وَكَانُوا لَا يَقْنُتُونَ فِي الْفَجْرِ» ثُمَّ قَالَ «يَا بُنَيَّ مُحْدَثٌ»
