Shah Abdul Aziz writes that some important guests once came to visit Khwaja Baaqi Billah, while he was completely destitute with nothing to eat. There was a restaurant/bakery near his house. When the shopkeeper saw these saintly people gathering at Khwaja’s house, at an inappropiate time, he filled a large tray with various kinds of food and took it to the house.
Khwaja Saheb asked: “What is this?”
He answered: “Khwaja Saheb, I have seen some guests arriving at your place and I have brought some food for the guests. Please accept it.”
Khwaja Saheb was very pleased and later, in his extreme pleasure he said spontaneously: “Ask of me whatever you wish to ask.”
The shopkeeper thought for a while and said: “Please make me just like yourself.”
Hazrat thought for a while as he hesitated and then said: “Ask anything else.”
Again the man replied: “No, that is what I would like.”
As he had already told the man to request whatever he wished, and the man repeatedly insisted on the same thing three times, Khwaja took him into his room and locked the door from the inside. It is not known what kind of spiritual attentions (Tawajjuh) Khwaja showered on him.
When after a while they both emerged from the room, they both were completely alike and identical, even in outward (physical) appearance. Hazrat Khwaja came out as he went in, while the shopkeeper-cook was in a high state of ecstacy. Soon afterwards he passed away. May Allah grant him a high rank in the hereafter. He lies buried near the grave of Hadhrat Baqi Billah (rahmatullah alayhi) in Delhi.
