Did the turning of the worshippers constitute acting upon the verse, rather than upon a report from a single narrator?

Question:
Honorable Shaykh! The questioner says: We learned that their turning was an act based on the verse, not on a report from a single narrator. How do you clarify this?

Answer:
The verse was not conveyed to them; the one who conveyed it to them was a single person. They did not hear the verse from the Messenger of Allah (peace and blessings be upon him); rather, they acted upon the report of a single narrator who informed them of the revelation of the Qur'an to the Messenger of Allah (peace and blessings be upon him). So, does one say that their acting upon the verse was that of an ignorant person who does not know how to derive evidence? Yes, they did not hear the verse nor were they present when it was revealed to the Messenger of Allah (peace and blessings be upon him); rather, this Companion informed them, and they acted upon his report. Yes.
