Man of Cakes
The great Chishti saint Khwaja Qutubuddin Bakhtiyar Kaki was named Qutubuddin by his parents; his title "Bakhtiyar," meaning "friend of fortune," was given to him by his Shaikh, Muinuddin Chishti. But how did he come by his other name, "Kaki," that is, "a man of cakes?" One day Qutubuddin was sitting near the tank known as Shamsiya in Delhi when some friends of his drew near and expressed a desire to eat hot cakes. He immediately thrust his hand into the water of the tank and drew forth exactly those cakes that his friends desired, and from that day he came to be called "Kaki."
