«بيني وبين كَنِّي ليلٌ دامسٌ وطريقٌ طامسٌ»
Between me and my desired refuge lie a dark night and a path whose traces are obscured.
«دامس» and «طامس» share most of their consonantal material but differ initially between dāl and ṭāʾ. Their place and manner of articulation are sufficiently related for the audible likeness to be noticed. Pairs of this kind illustrate the logic of muḍāriʿ jinās.
Their meanings are not interchangeable: the first evokes darkness and the second the obliteration or obscurity of a path. The contrast of meaning works alongside the closeness of sound.
