when anyone sits between the four parts of a woman and the parts (of the male and female) which are circumscised join together, then bath becomes obligatory.  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا قَعَدَ بَيْنَ شُعَبِهَا الأَرْبَعِ وَأَلْزَقَ الْخِتَانَ بِالْخِتَانِ فَقَدْ وَجَبَ الْغُسْلُ  

the Prophet said: "When the circumcised meets the circumcised then Ghusl is required." (Using translation from Tirmidhī 109)   

قَالَ رَسُولُ اللهِ ﷺ إِذَا جَاوَزَ الْخِتَانُ الْخِتَانَ فَقَدْ وَجَبَ الْغُسْلُ  

[Machine] "The Messenger of Allah ﷺ said, 'If one sits among a gathering of people and his circumcised area touches the circumcised area of another person, then it becomes obligatory to perform ritual washing.'"  

قَالَ رَسُولُ اللهِ ﷺ إِذَا جَلَسَ بَيْنَ الشُّعَبِ الْأَرْبَعِ ثُمَّ أَلْزَقَ الْخِتَانَ بِالْخِتَانِ فَقَدْ وَجَبَ الْغُسْلُ  

the Prophet said: "When the circumcised meets the circumcised then Ghusl is required." (Using translation from Tirmidhī 109)   

قَالَ رَسُولُ اللَّهِ ﷺ «إِذَا جَاوَزَ الْخِتَانُ الْخِتَانَ فَقَدْ وَجَبَ الْغُسْلُ»  

"The Messenger of Allah said: 'When the two circumcised parts meet, and (the tip of the penis) disappears, then bath is obligatory.'" (Using translation from Ibn Mājah 611)   

قَالَ رَسُولُ اللَّهِ ﷺ «إِذَا الْتَقَى الْخِتَانَانِ فَقَدْ وَجَبَ الْغُسْلُ»  

[Machine] On the authority of the Prophet, ﷺ , he said: "When a person sits between the four limbs and then exerts himself, he must perform the ritual washing, whether he ejaculates or not."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا قَعَدَ بَيْنَ شُعَبِهَا الْأَرْبَعِ ثُمَّ أَجْهَدَ نَفْسَهُ فَقَدْ وَجَبَ الْغُسْلُ أَنْزَلَ أَوْ لَمْ يُنْزِلْ  

when anyone sits between the four parts of a woman and the parts (of the male and female) which are circumscised join together, then bath becomes obligatory. (Using translation from Abū Dāʾūd 216)   

"إِذا قَعَد بين شُعَبها الأرْبَع وألزَق الخِتانَ بالخِتْانِ فقد وَجَبَ الغُسْلُ" .
