The poetic expression بَيْنَ الضَّالِ وَالسَّلَمِ
Among the desert trees known as ḍāl and salam.
The two names refer to trees associated with the open desert. The description evokes a distinctive setting. The commentary considers that setting in relation to desert life and to the possible praising or disparaging implications of the poem.
The important interpretive principle is that a reference to a location or way of life is not automatically praise or blame. Its force comes from the speaker's broader purpose, the audience's assumptions, and the attributes attached to the person described.
