Does the practice of the Companions strengthen a mursal (report missing the Companion link) hadith, as some scholars state?

The questioner : Regarding this, we return to the same point: the three opinions on the ruling concerning acting upon an authentic hadith. When they say, for example, that it agrees with the scholars or agrees with the practice of the Companions, this agreement can strengthen and support a mursal (report missing the Companion link) hadith. It may be the independent legal reasoning (ijtihad) of the scholars.

The Shaykh : It strengthens the ruling, not the hadith. But that is not what they intend; they intend the hadith. I want to distinguish between these two.
