Is a husband entitled to verify the paternity of a child, especially if his wife had secretly spoken with a foreign man and fled from home twice, then he divorced her while she was pregnant and he claims the child is not his because he did not ejaculate inside her?

Merely ejaculating outside the womb or practicing coitus interruptus does not permit denying paternity. A child is attributed to the husband if there is a possibility that the child is his, even if the husband sees his wife committing adultery. It is not permissible to deny lineage that is شرعًا (legally/religiously) established based on modern medical means, such as DNA fingerprinting, nor is it permissible to prioritize it over li'an (oath of condemnation). The use of DNA fingerprinting to confirm the validity of lineages that are شرعًا established must be prevented to protect people's honor and lineages. The procedure of DNA fingerprinting must be restricted to judicial requests and specialized laboratories, with private sector involvement in conducting this test being prohibited.
