Correction and explanation of a hemistich in the story of Rustam and Suhrab

The story of Rustam and Suhrab is one of the two controversial stories of the Shahnameh, whose textual problems have not all been solved yet.In this article, a hemistich of this story characterizing Rustam is discussed in terms of its recordings and meaning. It appears in the Shahnameh manuscripts in twenty-six different forms, and in printed and edited versions of the book, in seven variations. In the end, the recording “ke az abr, peel ārad andar nahān is recommended. In this recording, the word abr is probably a metaphoric expression for “sword”. Thus, the meaning of the hemistich is: [Rustam can] kill an elephant with his sword and terminate it.
