"I said to my father: 'O my father! You offered Salat behind Messenger of Allah (S), Abu Bakr, Umar, Uthman, and Ali bin Abi Talib here in Al-Kufah for about five years. Did they say the Qunut?' He said: 'It is a newly invented matter my son.'"  

قُلْتُ لأَبِي يَا أَبَةِ إِنَّكَ قَدْ صَلَّيْتَ خَلْفَ رَسُولِ اللَّهِ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ وَعُثْمَانَ وَعَلِيِّ بْنِ أَبِي طَالِبٍ هَا هُنَا بِالْكُوفَةِ نَحْوًا مِنْ خَمْسِ سِنِينَ أَكَانُوا يَقْنُتُونَ قَالَ أَىْ بُنَىَّ مُحْدَثٌ  

There exists another narration from Abu Malik with similar meaning but with different chain.  

عَنْ أَبِي مَالِكٍ الأَشْجَعِيِّ بِهَذَا الإِسْنَادِ نَحْوَهُ بِمَعْنَاهُ
