Hasan bin Alī al-Hulwānī narrated to me, he said Yazīd bin Hārūn narrated to us, Hammām informed us, he said ‘Abū Dāwud al-A’mā entered upon Qatādah and when he stood, they said:
‘Indeed this one alleges he has met eighteen of the warriors of the battle of Badr’. Qatādah said: ‘This one was barely asking [about Ḥadīth] before the plague; he did not attend to anything from [seeking Ḥadīth] and he did not speak [to any scholars] regarding it. By Allah, al-Hasan did not narrate to us from a witness of the battle of Badr without an intermediary; and Sa’īd bin al-Musayyib did not narrate to us from a witness of the battle of Badr without an intermediary except from Sa’d bin Mālik’.

وَحَدَّثَنِي حَسَنُ بْنُ عَلِيٍّ الْحُلْوَانِيُّ، قَالَ حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَخْبَرَنَا هَمَّامٌ، قَالَ دَخَلَ أَبُو دَاوُدَ الأَعْمَى عَلَى قَتَادَةَ فَلَمَّا قَامَ قَالُوا إِنَّ هَذَا يَزْعُمُ أَنَّهُ لَقِيَ ثَمَانِيَةَ عَشَرَ بَدْرِيًّا . فَقَالَ قَتَادَةُ هَذَا كَانَ سَائِلاً قَبْلَ الْجَارِفِ لاَ يَعْرِضُ فِي شَىْءٍ مِنْ هَذَا وَلاَ يَتَكَلَّمُ فِيهِ . فَوَاللَّهِ مَا حَدَّثَنَا الْحَسَنُ عَنْ بَدْرِيٍّ مُشَافَهَةً . وَلاَ حَدَّثَنَا سَعِيدُ بْنُ الْمُسَيَّبِ عَنْ بَدْرِيٍّ مُشَافَهَةً إِلاَّ عَنْ سَعْدِ بْنِ مَالِكٍ .
