What is the authenticity of the story of Abdullah ibn al-Mubarak's dream, which indicates that God accepted the pilgrimage of all pilgrims due to the stance of the Syrian cobbler who did not perform Hajj, and does this story have a basis in history books, and what is its source, and can such a story be relied upon?

We have not found any origin for the story of the shoemaker that some preachers mention. It bears signs of fabrication, for how could a saint slap his cheek and ask his neighbor for food when he is self-sufficient with the money for Hajj, and was forbidden from doing so?

As for the similar story of Abdullah ibn al-Mubarak, mentioned by Ibn Kathir in "Al-Bidaya wa al-Nihaya," it states that on his way to Hajj, he found a poor girl taking a dead bird from the garbage dump. She informed him that she and her brother had no sustenance except what was thrown in the garbage, and that their father had been wronged and killed. Ibn al-Mubarak then ordered his agent to give the girl the remaining money he had for Hajj, saying that this was better than their Hajj this year, and then he returned.
