مُحْتَوٍ عَلَى زِحَامٍ وَنَحِيبٍ
Containing a crowd and the sound of sobbing.
Ziḥām means a dense crowd; naḥīb means audible lamentation or sobbing. Their similar endings give the clause a rhymed-prose effect, though the words mean very different things.
Suspense now replaces aimless wandering: Why are so many people gathered, and what is causing their cries?
