"She is informing you about her companion who has committed illegal sexual intercourse with her."

Abu Jamra said, "I was an interpreter between Ibn 'Abbas and the people." Some people said, "A ruler should have two interpreters."
Sahih al-Bukhari Book 93, Hadith 56
← Previous Hadith A bedouin came and said, "O Allah's Messenger (ﷺ)! Judge between us according to Allah's Book (Laws)." His opponent stood up and said, "He has said the truth, so judge between us according to Allah's Laws." The bedouin said, "My son was a laborer for this man and committed illegal sexual intercourse with his wife. The people said to me, 'Your son is to be stoned to death,' so I ransomed my son for one hundred sheep and a slave girl. Then I asked the religious learned men and they said to me, 'Your son has to receive one hundred lashes plus one year of exile.' " The Prophet (ﷺ) said, "I shall judge between you according to Allah's Book (Laws)! As for the slave girl and the sheep, it shall be returned to you, and your son shall receive one-hundred lashes and be exiled for one year. O you, Unais!" The Prophet (ﷺ) addressed some man, "Go in the morning to the wife of this man and stone her to death." So Unais went to her the next morning and stoned her to death.

Sahih al-Bukhari Book 93, Hadith 55 Next Hadith → That Abu Sufyan bin Harb told him that Heraclius had called him along with the members of a Quraish caravan and then said to his interpreter, "Tell them that I want to ask this (Abu Sufyan) a question, and if he tries to tell me a lie, they should contradict him." Then Abu Sufyan mentioned the whole narration and said that Heraclius said to the inter Peter, "Say to him (Abu Sufyan), 'If what you say is true, then he (the Prophet) will take over the place underneath my two feet.' "
