Is it possible that a sound mursal Tabi'i took from a weak Tabi'i if his hadith came with a complete chain through another route?

The questioner : May Allah preserve you. If this sound mursal, meaning the one from the Tabi'un, came through another route with the same text, but as a complete chain from another Tabi'i who is weak, is it not possible that the first mursal Tabi'i took it from the weak Tabi'i who is in the complete chain? This is also possible.

The Shaykh : This is theoretically possible, without a doubt. But here, too, it is necessary to conduct a study regarding the status of this weak narrator.

The questioner : What Allah willed.
