كأن قلوب الطير رطبًا ويابسًا
As though the birds' hearts, fresh and dried…
The example mentions fresh and dried hearts on one side, and jujubes and old dried dates on the other. The first group lists subjects; the second group supplies corresponding comparison terms. The fresh hearts match the jujubes, and the dry hearts match the old dates.
In the enfolded form (malfūf), separate likenesses are packed as one group followed by another. Correct analysis recovers the individual pairings; the whole expression need not be treated as one indivisible composite image.
