Imaam Ahmed bin Hambal (rahimahullah) never called any of his Asaatizah by their names out of respect for them. Rather, he would refer to them by their titles.

(Aadaabul Muta‘allimeen)

Once, Imaam Ahmed (rahimahullah) was lying down due to some illness. In the middle of the discussion, someone mentioned the name of Ebrahim bin Tahmaan (rahimahullah). On hearing this name, Imaam Ahmed (rahimahullah) immediately sat up out of respect. He thereafter remarked, “It is inappropriate for the names of the elders to be mentioned whilst we are sitting and relaxing.”
