أَكْرَمْتُ الضُّيُوفَ وَخَاصَّةً كِبَارَهُمْ.
I honored the guests, especially their elders.
The elders are already included in “the guests.” Mentioning them separately marks special importance and can serve specific mention after general mention, a useful form of amplification.
It does not entail that the other guests were dishonored. Confusing prominence with exclusion mistakes a rhetorical spotlight for a restrictive negation.
