What is the authenticity of the story of Abu Bakr with the old woman whose needs he used to fulfill after the Fajr prayer, and what is its source?

The story of Abu Bakr Al-Siddiq (may Allah be pleased with him) serving a blind old woman is not established, and scholars have not found a complete origin for it. It has been reported with other very weak chains of narration due to the presence of unknown or very weak narrators in their chains, such as Abu Salih Al-Ghifari, Hajjaj bin Shaddad, Rishdin bin Sa'd, and Muhammad bin Umar Al-Waqidi, who is known for his weakness and whose narrations the Imams avoided. The established virtues of Abu Bakr in the Islamic sources surpass this story.
