Is it possible for a narrator who is abandoned or a liar to appear in the chain of a hadith that is being traced to its sources as authentic?

The questioner : In the book *Irwaa' al-Ghalil*, I saw that in some places you mentioned a hadith of a man, meaning it appears that he is abandoned or a liar. You said, "And we have known the authenticity of his hadith," and you mentioned it as a corroborating narration. Is it possible, if we are certain of the authenticity of a hadith through a narration in another place, to mention the abandoned or lying narrator in the verification as well, in the context of the hadith?

The Shaykh : What do you mean? Do you mean tracing his hadith to its sources?

The questioner : Yes, we trace his hadith to its sources and say, "Even though he is a liar, his hadith is authentic."

The Shaykh : And what prevents this? If the Messenger (peace and blessings be upon him) says in the authentic hadith , then no matter what his status is, he is better than that lying devil!

The questioner : What Allah willed.
