Not saying the Qunut

It was narrated from Anas that:

The Messenger of Allah (ﷺ) said the Qunut for one month, supplicating against one of the 'Arab tribes, then he stopped doing that."

أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا مُعَاذُ بْنُ هِشَامٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَنَتَ شَهْرًا يَدْعُو عَلَى حَىٍّ مِنْ أَحْيَاءِ الْعَرَبِ ثُمَّ تَرَكَهُ ‏.‏

It was narrated from Abu Malik Al-Ashja'i that his father said:

"I prayed behind the Messenger of Allah (ﷺ) and he did not say the Qunut, and I prayed behind Abu Bakr and he did not say the Qunut, and I prayed behind Umar and he did not say the Qunut, and I prayed behind Uthman and he did not say the Qunut, and I prayed behind Ali and he did not say the Qunut." Then he said: "O my son, this is an innovation."

أَخْبَرَنَا قُتَيْبَةُ، عَنْ خَلَفٍ، - وَهُوَ ابْنُ خَلِيفَةَ - عَنْ أَبِي مَالِكٍ الأَشْجَعِيِّ، عَنْ أَبِيهِ، قَالَ صَلَّيْتُ خَلْفَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَلَمْ يَقْنُتْ وَصَلَّيْتُ خَلْفَ أَبِي بَكْرٍ فَلَمْ يَقْنُتْ وَصَلَّيْتُ خَلْفَ عُمَرَ فَلَمْ يَقْنُتْ وَصَلَّيْتُ خَلْفَ عُثْمَانَ فَلَمْ يَقْنُتْ وَصَلَّيْتُ خَلْفَ عَلِيٍّ فَلَمْ يَقْنُتْ ثُمَّ قَالَ يَا بُنَىَّ إِنَّهَا بِدْعَةٌ ‏.‏
