The ruling on a woman admitting to her husband and his denial

Question:
If a slave woman commits zina (unlawful sexual intercourse) and becomes pregnant from this zina, and when asked who the man was who committed zina with her, she says "that one," and the one accused denies it, what is the ruling of the Shari'ah in this case, and are medical reports relied upon?

Answer:
No, the principle in the Shari'ah requires ignoring this and not investigating such matters. The woman's admission that a specific man committed zina with her is not accepted; this is not taken into account. She is only held accountable for her own admission against herself. As for him, he is not touched except by his own zina, or by his own admission four times in this month, four months, or four admissions from him.
