The moon was asked: "O son of one night, what are you?"
"Milk of a ewe whose folk have camped in an arid quarter," said the moon. [A singsong reply that rhymes in Arabic with the asker's question, as do all the moon's replies up to night thirteen.]
"And on the second night, what are you?" the moon was asked.
"Talk between two domestics [of different households], full of slander and untruth," said the moon.
