They said: “By Allah! truly thou art in thine old wandering mind.”
“They” must be the people around him, before
the brothers actually arrived.

calumny that their father was an old dotard, and
everybody around believed it, even after its authors had
to give it up. Thus lies die hard, once they get a start.
