bayhaqi:781Ibn Bukayr > Mālik > Abū al-Naḍr a freed slave of ʿUmar b. ʿUbaydullāh > Abū Salamah b. ʿAbd al-Raḥman > Saʾalt ʿĀʾishah Mā Yūjib al-Ghusl

I asked Aisha, the mother of the believers, "What necessitates performing the ritual bath (ghusl)?" She replied, "Do you not know? Your likeness is like that of a young rooster, you hear the hen coo and you respond by crowing along with her. If the circumcision has surpassed the circumcision (i.e., sexual intercourse has taken place), then the ritual bath becomes obligatory."  

البيهقي:٧٨١وَبِإِسْنَادِهِ قَالَ حَدَّثَنَا ابْنُ بُكَيْرٍ ثنا مَالِكٌ عَنْ أَبِي النَّضْرِ مَوْلَى عُمَرَ بْنِ عُبَيْدِ اللهِ عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ أَنَّهُ قَالَ

سَأَلْتُ عَائِشَةَ أُمَّ الْمُؤْمِنِينَ ؓ مَا يُوجِبُ الْغُسْلَ؟ فَقَالَتْ أَتَدْرِي مَا مَثَلُكَ يَا أَبَا سَلَمَةَ مَثَلُكَ مَثَلُ الْفُرُوخِ تَسْمَعُ الدِّيَكَةَ تَصِيحُ فَتَصْرُخُ مَعَهَا إِذَا جَاوَزَ الْخِتَانُ الْخِتَانَ فَقَدْ وَجَبَ الْغُسْلُ

malik:2-73Mālik > Abū al-Naḍr a freed slave of ʿUmar b. ʿUbaydullāh > Abū Salamah b. ʿAbd al-Raḥman b. ʿAwf

Yahya related to me from Malik from Abu'n Nadr, the mawla of Umar ibn Abdullah that Abu Salamaibn Abdar-Rahman ibn Awf related that he had asked A'isha, the wife of the Prophet ﷺ what made ghusl obligatory. She said, "Do you know what you are like, Abu Salama? You are like a chick when it hears the cocks crowing and so crows with them. When the circumcised part passes the circumcised part, ghusl is obligatory."  

مالك:٢-٧٣وَحَدَّثَنِي عَنْ مَالِكٍ عَنْ أَبِي النَّضْرِ مَوْلَى عُمَرَ بْنِ عُبَيْدِ اللَّهِ عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ

أَنَّهُ قَالَ سَأَلْتُ عَائِشَةَ زَوْجَ النَّبِيِّ ﷺ مَا يُوجِبُ الْغُسْلَ فَقَالَتْ هَلْ تَدْرِي مَا مَثَلُكَ يَا أَبَا سَلَمَةَ مَثَلُ الْفَرُّوجِ يَسْمَعُ الدِّيَكَةَ تَصْرُخُ فَيَصْرُخُ مَعَهَا إِذَا جَاوَزَ الْخِتَانُ الْخِتَانَ فَقَدْ وَجَبَ الْغُسْلُ
