Is the story of Tha'labah ibn 'Abd al-Rahman authentic, and is it permissible to narrate it—even with a clarification of its weakness if necessary—due to the positive impact it has on people's souls?

The story mentioned about Tha'labah ibn Abd al-Rahman is very weak from several perspectives: Firstly, the weakness of its narrators, such as Sulaym ibn Mansour, Mansour ibn Ammar, and al-Munkadir ibn Muhammad. Secondly, the discrepancy of the hadith (definition)'s text with known facts, as the verse "Your Lord has not forsaken you, nor has He detested [you]" was revealed in Mecca before the Hijrah (definition), while the story claims its revelation in Medina after the Hijrah, and this is contradictory. Scholars have ruled it as fabricated and extremely weak, so it is not permissible to narrate it except to demonstrate its weakness.
