“About the case of a man who claims to have married a woman in the presence of witnesses and her guardian but she denies it and the sister of this woman presents testimony that the man has married her in the presence of witnesses and her guardian but she does not prove the time of marriage. Ali ibn al-Husayn (a.s.), issued a judgment in this case that said, ‘The testimony of the man is admitted and accepted and the testimony of the woman is not accepted because the husband is entitled to claim his conjugal right and her sister wants to destroy such right so she must not be taken as truthful and her testimony is unacceptable without specifying the time before her time or proof of consummation of marriage (the couple’s going to bed).”’
