«بعض الحيوان أسود»
Some animals are black.
“Some” designates part of the animal class, and blackness is affirmed of those instances. This is a particular affirmative.
“Some students have memorized the Qur’an” asserts that at least some students have that property. It does not entail that all remaining students lack it; the claim simply makes no commitment about them.
Thus logical “some” should not be confused with a conversational suggestion that the remaining members must be excluded.
