Shaqeeq bin Ebrahim (rahimahullah) mentions:

On one occasion, I was walking along the road with Imaam Abu Hanifah (rahimahullah), proceeding to visit a person who was sick. As we were walking, a certain person (who was on the same road) saw Imaam Abu Hanifah (rahimahullah) from afar. As he saw Imaam Abu Hanifah (rahimahullah), he tried to hide from him and began to walk on a different road.
