bayhaqi:3156Abū Bakr Muḥammad b. al-Ḥasan b. Fūrak > ʿAbdullāh b. Jaʿfar > Yūnus b. Ḥabīb > Abū Dāwud > Abū ʿAwānah > Abū Mālik al-Ashjaʿī

[Machine] I said to my father, "Oh father, haven't you prayed behind the Messenger of Allah ﷺ , and behind Abu Bakr, and behind Umar?" He replied, "Indeed, yes." I said, "So, were they not punctual in performing the Fajr prayer?" He said, "O my son, Tariq ibn Ashyam al-Ashja'i innovated something that no one who prayed behind him has preserved. He saw him innovating something while others have memorized it. So, the ruling is in favor of the one who has memorized it rather than him."  

البيهقي:٣١٥٦أَخْبَرَنَا أَبُو بَكْرٍ مُحَمَّدُ بْنُ الْحَسَنِ بْنِ فُورَكٍ أنبأ عَبْدُ اللهِ بْنُ جَعْفَرٍ ثنا يُونُسُ بْنُ حَبِيبٍ ثنا أَبُو دَاوُدَ ثنا أَبُو عَوَانَةَ عَنْ أَبِي مَالِكٍ الْأَشْجَعِيِّ قَالَ

قُلْتُ لِأَبِي يَا أَبَتِ أَلَيْسَ قَدْ صَلَّيْتَ خَلْفَ رَسُولِ اللهِ ﷺ وَخَلَفَ أَبِي بَكْرٍ وَخَلَفَ عُمَرَ؟ قَالَ بَلَى قُلْتُ فَكَانُوا يَقْنُتُونَ فِي الْفَجْرِ؟ قَالَ يَا بُنِيَّ مُحْدَثَةٌ طَارِقُ بْنُ أَشْيَمَ الْأَشْجَعِيُّ لَمْ يَحْفَظْهُ عَمَّنْ صَلَّى خَلْفَهُ فَرَآهُ مُحْدَثًا وَقَدْ حَفِظَهُ غَيْرُهُ فَالْحُكْمُ لَهُ دُونَهُ
