How sound is the story of two snakes transforming into two gold necklaces due to a girl's perseverance in sending blessings upon Muhammad and the Family of Muhammad?

The story mentioned has no origin or chain of narration, and it circulates in forums of the people of innovation without a source. A Muslim must follow the methodology of verification and scrutiny in narrations, acting upon the words of the Almighty: "And do not pursue that of which you have no knowledge." This specific story might be among the fables of the Rafidah, who deem lying permissible. What is established in Sharia is the recommendation of specific remembrances for different occasions, and not restricting oneself to sending prayers upon the Prophet (peace be upon him).
