Sahban Wa'il was regarded as unparalleled in eloquence because he would speak for an entire year before an audience without repeating a single word. And if repetition occurred, he would express it in a different way. Among the courtesies expected of the companions of kings, this is one of them.
Though speech may be charming and sweet,
Worthy of praise and approval,
Once it is said, do not repeat it again,
For just like with sweets, once is enough.
