What is meant when it is said that a narrator is or is not a حافظ الحديث as in for example
شريك: ليس بالحافظ عند أهل الحديث
This is an expression used to show a slight defect in a narrator’s memory. It does not necessarily mean that his memory is totally weak. Rather it is just not as strong as other reliable narrators.
It is from the lightest words denote a defect.
