It was narrated from 'Amr bin Shu'aib, from his father, from his grandfather, that Marthad bin Abi Marthad Al-Ghanawi --a strong man who used to take the prisoners from Makkah to Al-Madinah-- said: "I arranged with a man to bring him (from Makkah to Al-Madinah). There was a prostitute in Makkah who was called 'Anaq, and she was his friend. She came out and saw my shadow on the wall, and said: 'Who is this? Marthad? Welcome, O Marthad, come tonight and stay at our place.' I said: 'O 'Anaq, the Messenger of Allah has forbidden adultery.' She said: 'O people of the tents, this porcupine is the one who is taking your prisoners from Makkah to Al-Madinah!' I headed toward (the mountain of) Al-Khandamah, and eight men came after me. They came and stood over my head, and they urinated, and their urine reached me, but Allah caused them not to see me. Then I went to my companion (the prisoner) and brought him to Al-Arak, where I undid his fetters. Then I came to the Messenger of Allah and said: 'O Messenger of Allah, shall I marry 'Anaq?' He remained silent and did not answer me, then the following was revealed: 'And the adulteress-fornicator, none marries her except an adulterer-fornicator or an idolater.' He called me and recited them to me and said: 'Do not marry her.'"
