«الْكَرَمُ ـ ثَبَّتَ اللَّهُ جَيْشَ سُعُودِكَ ـ يَزِينُ»
Generosity—may God preserve the host of your good fortunes—adorns a person.
The underlying statement is al-karam yazīn, 'generosity adorns'. A blessing is inserted between its two parts. Jaysh suʿūdika, 'the army of your good fortunes', personifies good fortune as an organized force.
The effect is both literary and graphic: the message combines sincere-sounding honorific language with exact alternation of dotted and dotless words. The inserted prayer does not break the grammatical sense of the praise.
