أبو داود:٧٩٩حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ أَخْبَرَنَا هَمَّامٌ وَأَبَانُ بْنُ يَزِيدَ الْعَطَّارُ عَنْ يَحْيَى عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ

عَنْ أَبِيهِ بِبَعْضِ هَذَا وَزَادَ فِي الأُخْرَيَيْنِ بِفَاتِحَةِ الْكِتَابِ وَزَادَ عَنْ هَمَّامٍ قَالَ وَكَانَ يُطَوِّلُ فِي الرَّكْعَةِ الأُولَى مَا لاَ يُطَوِّلُ فِي الثَّانِيَةِ وَهَكَذَا فِي صَلاَةِ الْعَصْرِ وَهَكَذَا فِي صَلاَةِ الْغَدَاةِ
