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.'"  

فَدَعَوْتُ رَجُلاً لأَحْمِلَهُ وَكَانَ بِمَكَّةَ بَغِيٌّ يُقَالُ لَهَا عَنَاقُ وَكَانَتْ صَدِيقَتَهُ خَرَجَتْ فَرَأَتْ سَوَادِي فِي ظِلِّ الْحَائِطِ فَقَالَتْ مَنْ هَذَا مَرْثَدٌ مَرْحَبًا وَأَهْلاً يَا مَرْثَدُ انْطَلِقِ اللَّيْلَةَ فَبِتْ عِنْدَنَا فِي الرَّحْلِ قُلْتُ يَا عَنَاقُ إِنَّ رَسُولَ اللَّهِ ﷺ حَرَّمَ الزِّنَا قَالَتْ يَا أَهْلَ الْخِيَامِ هَذَا الدُّلْدُلُ هَذَا الَّذِي يَحْمِلُ أُسَرَاءَكُمْ مِنْ مَكَّةَ إِلَى الْمَدِينَةِ فَسَلَكْتُ الْخَنْدَمَةَ فَطَلَبَنِي ثَمَانِيَةٌ فَجَاءُوا حَتَّى قَامُوا عَلَى رَأْسِي فَبَالُوا فَطَارَ بَوْلُهُمْ عَلَىَّ وَأَعْمَاهُمُ اللَّهُ عَنِّي فَجِئْتُ إِلَى صَاحِبِي فَحَمَلْتُهُ فَلَمَّا انْتَهَيْتُ بِهِ إِلَى الأَرَاكِ فَكَكْتُ عَنْهُ كَبْلَهُ فَجِئْتُ إِلَى رَسُولِ اللَّهِ ﷺ فَقُلْتُ يَا رَسُولَ اللَّهِ أَنْكِحُ عَنَاقَ فَسَكَتَ عَنِّي فَنَزَلَتِ { الزَّانِيَةُ لاَ يَنْكِحُهَا إِلاَّ زَانٍ أَوْ مُشْرِكٌ } فَدَعَانِي فَقَرَأَهَا عَلَىَّ وَقَالَ لاَ تَنْكِحْهَا  

from his father, from his grandfather, who said "There was a man named Marthad bin Abi Marthad, and he was a man who would carry captives from Makkah to Al-Madinah." He said: "And there was a prostitute woman in Makkah called 'Anaq, who was a friend of his. He had promised a man from the captives of Makkah that he would transport him, and he said: 'So I came until I reached one of the walls of Makkah on a moon-lit night.' He said "'Anaq came along and she saw the darkness of my shadow next to the wall. When she reached me she recognized me and said: "Marthad?" So I replied: "(Yes it is) Marthad." She said: "Welcome, come and spend the night with us." I said: "O 'Anaq! Allah has made illicit sexual relations unlawful." So she said: "O people of the tents! That is the man who takes your captives away!" He said: "Eight people followed me, and I went through the passes of Al-Khandamah. I stopped at a cave and entered it. They came until they stood over my head, and they began urinating, their urine falling on my head. Yet Allah made them unable to see me. He said: 'Then I went back. I returned to my companion to transport him - and he was a heavy man - until I reached Al-Idhkir. There I removed his shackles to make him easier to carry, since he was exhausting me, until I arrived at Al-Madinah. I went to the Messenger of Allah ﷺ and I said "O Messenger of Allah! May I marry 'Anaq? [I said this, two times] but the Messenger of Allah ﷺ was silent, and he did not reply to me at all until (the following) was revealed: The Zani marries not but a Zaniyah or a Mushrikah; and the Zaniyah, none marries her except a Zani or a Mushrik (24:3). So do not marry her.'" (Using translation from Tirmidhī 3177)
