Is there a difference between ("his hadith is recorded but not relied upon" and "weak")?

The questioner : His hadith is recorded but not relied upon.

The Shaykh : This is strange. No, no, now you have changed.

The questioner : There is a difference between "not relied upon" and "weak."

The Shaykh : Because Abu Hatim's statement "not relied upon" actually equates to a hasan hadith, provided there is no absolute weakening of it. Abu Hatim's statement regarding some narrators—we often weaken this—dozens of narrators from the trusted narrators of the two Sahihs, from the reliable imams, you find Abu Hatim saying "his hadith is not relied upon." This is frequent from him, very frequent. I do not understand an absolute weakening from Abu Hatim's word "not relied upon"; rather, it is not relied upon in the rank of the trusted ones whose hadith is authentic. A thought came to my mind during yesterday's meeting; I should have mentioned it, but I do not know what the occasion was, so the thought passed, and now it has returned!

The questioner : Praise be to Allah.

The Shaykh : But perhaps I will remember it after I finish answering this. I was surprised when I said that he says to his son, "move it from the book of weak narrators," and yet he weakens it. If his weakening, as I said last, is "not relied upon," then this is not a contradiction of what I mentioned earlier. But if it is in your mind, even after... that he says, "move it from al-Bukhari's book of weak narrators, and it is weak," this is something I do not imagine.

The questioner: May Allah will it.

The Shaykh : As for "not relied upon," that is reasonable!

The questioner : Now, the thought, before I forget it for you.
