«زِينَةً بَيْنَ الْأَنَامِ وَمَزْنَةً عِنْدَ الْأَوَامِ»
An adornment among people and a rain-bearing cloud at a time of intense thirst.
Anām means people or creatures; awām denotes intense thirst. Despite their echo, the terms are not synonyms.
The first image concerns public recognition; the second uses maznah (a rain-bearing cloud) to portray the benefit of knowledge when someone is thirsty or in need. The similar endings create rhymed prose while the meanings diverge.
