Abu Amr said:

We used to hear the Hadeeth, and then present it to our companions (i.e. the People of Hadeeth), just as we would present a fake Dirham to a Teller, whatever they recognized we [accepted and] took, and whatever they rejected we [abandoned and] left.


[1] Tareekh Ibn ‘Asaakir 35/186

قال الأوزاعي: إن كنا لنسمع الحديث فنعرضه على أصحابنا كما نعرض الدرهم الزائف على الصيارفة فما عرفوا أخذنا وما أنكروا تركنا
