Some time ago our beloved brother Abul 'Abbaas Moosaa Richardson posted an article dealing refuting the claims that the Imaams of Hadeeth never used harsh criticism. The article as I know it was entitled "Shaikh Muqbil and Islaamic Jarh" or something to that effect; however, I think it was posted here on ST under a different name. If someone could respond with the link to that thread, I'd appreciate it, jazaakumu Allaahu khayran.
