The word "Tazkiah" has been mentioned several times
and in different forms in the Holy Quran. It means the attestation of
someone’s honorable record, or to purify one’s self. For instance, the
following verses spoke of "Tazkiah":
"Truly he succeeds that purifies it,"
"Hast thou slain an innocent person,"
"(To announce) to thee the gift of a holy son."
and
"That is (the course making for) most virtue and
purity amongst you."
The meaning of the first verse is to purify one’s
self from evil characteristics which develop from corrupt nutrition,
excessive speech, anger, envy, greed, self and material worship, conceit
and vanity. This type of purification is performed by abandoning such
traits, and adhering to the noble characteristics which contradict the
above mentioned ones.
The second verse means: Have you killed someone whom,
I attest to his honorable record, for he has not committed a crime or an
action, which necessitates punishing.
The third verse speaks of granting a prophet a
virtuous son made pure from all sins, and whose nations conform to
goodness.
Lady Fatima Zahra (As) is Zakiyah in all the above
mentioned meanings. This is understood from the verse of purification,
which we have already discussed, and concluded that She (A.S.)
was pure of all abominations or "Rijs."
As for the fourth verse, you can refer to the study in regard to her
name Al-Mubarakah", for here we have explained the purification meant in
this verse.
