Once some noblemen of Nishapur went to visit Hazrat Ahmad Harb رحمه الله. Whilst they were sitting in conversation with him, the son of Hazrat Ahmad Harb رحمه الله passed nearby on the outside. He was playing the guitar and walking like a drunken man totally absorbed in music. The noblemen stared in amazement at the son. Hazrat Ahmad Harb رحمه الله who was obviously embarrassed said; “Once some food came from my neighbour and we ate of it. The same night I had relations with my wife, and this son was conceived. It later transpired that the food had come to the neighbour from the ruler. (The consequence of eating doubtful food was the wayward child.)
