Hadith 31-118

وَبِهذَا الإِسنادِ عَنْ عَلِيٍ‏ عَلَيْهِ السَّلامُ قالَ: إِذا سُئِلَت المَرْأَةُ مَن فَجَرَ بِكِ؟ فَقالَتْ: فُلانٌ، ضُرِبَتْ حَدَّينِ حَدَّاً لِفِريَتِها عَلَى الرَّجُلِ، وَحَدَّاً لِما أَقَرَّت عَلَى نَفسِها.

According to the same documentation, Ali (a.s.) said, “If a woman is asked: ‘Who has committed adultery with you?” and she answers, ‘So and so has done so” then she should be punished twice: once for accusing a man, and the second one for confessing to having committed adultery.”
