What is the difference between "فَأَجَاءَهَا" and "جَاءَهَا," and what is the significance of using the former in the verse?

The Almighty's saying: "So the pangs of childbirth drove her" means childbirth compelled and necessitated her. The verb "جاء" (ja'a) is intransitive, while "أجاء" (aja'a) is transitive, and its origin is "جاء" (ja'a). Thus, it carries the meaning of "جاء" with an added emphasis. Mary endured severe childbirth pains, which forced her to seek refuge by the trunk of a palm tree. Her pregnancy was like that of other women, even though its origin was miraculous.
