The Stars Foretell Shaghad's Treachery

From C9.2, Rostam Comes to Kabul for His Brother. It illustrates C9.2.5–14:

C9.2.5
From Kashmir and Kabul the sages came,Astrologers and chiefs of honored name.
C9.2.6
They worshipped God and sought out knowledge, wiseIn Indian tables used to read the skies.
C9.2.7
They reckoned all the heavens to exploreWhat that fair child might find in fate’s vast store.
C9.2.8
The readers of the stars, in wonder caught,Looked at each other, troubled by their thought.
C9.2.9
They spoke to Zal, the son of Sahm, and said,“O heir of those whose stars shone overhead,
C9.2.10
We searched the heavens’ secrets, sphere by sphere;They hold no love for this young child so dear.
C9.2.11
When this fair infant comes at last of age,And enters on the valiant warrior’s stage,
C9.2.12
He will destroy the house of Sahm one day,And bring the line of Nariman’s decay.
C9.2.13
Through him Sistan will ring with troubled cries,And in Iran great tumult will arise.
C9.2.14
He will make bitter every person’s years,Then from this world he quickly disappears.”
