عَنْ أَبِي مَالِكٍ الْأَشْجَعِيِّ قَالَ: قُلْتُ لِأَبِي: يَا أَبَتِ! إِنَّكَ قَدْ صَلَّيْتَ خَلْفَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَعُمَرَ وَعُثْمَانَ وَعَلِيٍّ هَٰهُنَا بِالْكُوفَةِ قَرِيبًا مِنْ خَمْسِ سِنِينَ، أَكَانُوا يَقْنُتُونَ؟ قَالَ: أَيْ بُنَيَّ مُحْدَثٌ
Abu Malik Ashja'i says: I said to my father: O my dear father, indeed you have prayed behind the Messenger of Allah (peace and blessings be upon him), Sayyiduna Umar, Sayyiduna Uthman (may Allah be pleased with them), and here in Kufa behind Sayyiduna Ali (may Allah be pleased with him) for five years; so did these people recite Qunoot? He said: O my beloved son, this is a new thing.
