How sound is the Hadith: "Learning a verse or teaching it is better in the sight of Allah than sixty years of worship"?

The Hadith: "Whoever learns two Hadiths by which he benefits himself, or teaches them to others, they will be better for him than sixty years of worship," is fabricated. This is due to the presence of "Nufay' ibn al-Harith, Abu Dawud al-A'ma," who was a liar and fabricated Hadiths; the presence of an unknown person whose kunya is Abu al-Hasan; and "Hamzah ibn Hassan," who is unknown; and "Baqiyyah ibn al-Walid," who practiced Tadlis al-Taswiyah. Thus, the Hadith is full of defects and is not authentic.
