The Prophet ﷺ prohibited that one, i.e. man, should walk between two women.  

أبو داود:٥٢٧٣ – حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى بْنِ فَارِسٍ حَدَّثَنَا أَبُو قُتَيْبَةَ سَلْمُ بْنُ قُتَيْبَةَ عَنْ دَاوُدَ بْنِ أَبِي صَالِحٍ الْمُزَنِيِّ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ

أَنَّ النَّبِيَّ ﷺ نَهَى أَنْ يَمْشِيَ يَعْنِي الرَّجُلَ بَيْنَ الْمَرْأَتَيْنِ
