What is the meaning of a woman passing in front of a worshiper as an中断 to prayer? And is it necessary to repeat the prayer, and does this ruling apply to a female child under the age of five?

A woman passing in front of a praying person does not invalidate or interrupt the prayer according to the majority of scholars, who cite the hadith of Abu Sa'id that the Messenger of Allah (peace be upon him) said: "Nothing interrupts the prayer."
