What is the meaning of their saying: "a valid hadith" and "a hadith whose chain of narration is valid"? Is there a difference between them?

The questioner : A hadith whose chain of narration is valid and a valid hadith.

The Shaykh : Perhaps you know that the validity of a hadith is either established by a single chain of narration or established by a group of chains of narration. A hadith that is established by a group of chains of narration, where each chain on its own is weak, but the weak chains, if their weakness is not severe, strengthen one another. If the weak chains are isolated, and a single hadith is transmitted through them, then this hadith becomes valid by the sum of these chains and these routes. In this case, it is said: "a valid hadith."
As for when a hadith comes with a valid chain of narration, it is said: "a hadith whose chain of narration is valid." Not every hadith that is called "a valid hadith" has a valid chain of narration. Its chains of narration may be weak, but their sum gave this hadith this validity; so it is called "a valid hadith" to distinguish it from the hadith whose chain of narration is valid.

The questioner : Is the hadith with the valid chain of narration stronger than the valid hadith?

The Shaykh : No, that is a second matter, that is a second matter. After you have known the difference, as for which one is stronger, the issue differs. If a hadith comes with ten hadiths through ten chains of narration, and every chain has weakness due to the narrator's memorization, this hadith is more valid than the hadith whose chain of narration is valid. Because the group of narrators, even if there is weakness in their memorization, indicates that they have memorized this hadith. The memorization of these people, despite the weakness of each individual on his own, instills in the soul a greater reassurance of the hadith's validity than the reassurance in the validity of a hadith narrated by a single individual.
