Hinda was extremely pretty and beautiful...

Hinda was extremely pretty and beautiful, and Yazeed was deeply infatuated with her, despite knowing her loath for him; Yazeed wants to marry her but she adamantly refuses; she is forced into marriage with Yazeed; (it is this same Hinda who visits the Kerbala survivors in Damascus prison, to discover that they are the Ahlal-bayt, and not ordinary rebels as maintained by Yazeed).

Now, Hinda had her servants/helpers and one of them was this person who Kumayl was to meet in Yazeed's palace; Yazeed kept this helper (of Hinda) and granted him the privilege of any single wish to be honoured, out of Yazeed's love for Hinda. So Kumayl was to see this person in Yazeed's palace and the prayer leader explains to Kumayl the way to get to meet this helper in Yazeed's palace.

Kumayl was to pass through the various security barriers with confidence and act as if he is a frequent visitor to the palace and knows his way around.
