the Twelvers followed) was
that
Ja'far
al-Sadiqhad
explicitly
designated
Isma'il as the next imam, and
that
a subsequent designation of another
son—supposing it had occurred—could not validly supersede the first
designation.
Al-Afdal
claimed
that
al-Mustansir had designated al-
Musta'li on his deathbed, but it was understandable
that
pious Isma'ilis
should hold by the earlier designation
of
Nizar.
Nevertheless, onNizar's
death a difficulty arose. Nizar seems to have designated no one of his
sons as his successor; at any
rate,
no Nizarid rose to claim the imamate.
Who
then
was the imam of the rebel Isma'ilis (who now called them-
selves
Nizaris)?

Before
long, many outsiders and probably some Nizari Isma'ilis
believed
that
a son or grandson of Nizar had been smuggled out of
Egypt
and was kept secretly at Alamut. But we have no evidence
that
this was done, and some evidence
that
it was not: later, the Egyptian
government could claim to know
that
all the male descendants of
Nizar
were quiescent; the notion of a descendant of Nizar being at
Alamut
had to take the form of his having been a posthumous son by
a slave girl, and hence unknown in Cairo. At any
rate,
at Alamut no
account seems to have been taken of the presence of any Nizarid. If we
may judge by bits and shreds of evidence in later Isma'ili works, no
imam at all was named, after Nizar. It was known
that
one of the
Nizarids must be he, but not which one. Eventually, it seems, Hasan-i
Sabbah, as the most important of the da'Is, was recognized as hujja,
"proof", of the imam. The term hujja had already been used, at least
informally, of a figure in the ideal spiritual hierarchy ranking next after
the imam; now its use seems to have become more precise: Hasan was
custodian of the Isma'ili mission until the imam should reappear, at
which
time he would point out the imam to the faithful.
When this interpretation was adopted we cannot tell, but
there
is
nothing against its having been adopted already in Hasan's lifetime;
perhaps it was accepted at the same time as his leadership of the whole
movement. We have still less way of knowing how Hasan himself felt
about the doctrine, which presumably had not been taught him by any
actual imam though it concerned the most ultimate
truths,
which
should come by ta'llm. Yet the imam had been inaccessible to the faith-
ful
before, in the days before the rise of the Fatimids, and Hasan might

The Nizaris are properly to be distinguished, not from "Musta'lians", but from the

and the Hafizls on the
other.
