Hadith 29:228
Yazid ibn Harun narrated to us, Hammam informed us, he said: Abu Dawud al-A’ma entered upon Qatadah. When he left, they said to him, "This man narrates from eighteen [people who participated in] Badr." He said, "This man was a beggar before the [plague of] al-Jarif; he would not be exposed to anything [i.e., he was not a scholar]. By Allah, al-Hasan did not narrate to us from anyone who participated in Badr face-to-face, nor did Sa’id ibn al-Musayyib narrate to us from anyone who participated in Badr face-to-face, except for Sa’d ibn Malik."
حدثنا يزيد بن هارون أخبرنا همام قال دخل أبو داود الأعمى على قتادة فلما خرج قالوا له هذا يروي عن ثمانية عشر بدريا قال هذا كان سائلا قبل الجارف لا يعرض لشيء فوالله ما حدثنا الحسن عن بدري مشافهة ولا حدثنا سعيد بن المسيب عن بدري مشافهة إلا عن سعد بن مالك
