وَعَنْ عَمْرِو بْنِ شُعَيْبٍ عَنْ أَبِيهِ عَنْ جده رضى اللَّه عَنهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: "لاَ يَحِلُّ لِرَجُلٍ أَنْ يُفَرِّقَ بَيْنَ اثْنَيْنِ إِلاَّ بِإِذْنِهِمَا" رَوَاهُ أَبُو دَاوُدَ وَالتِّرْمِذِيُّ وَقَالَ "حَدِيثِ حَسَنٍ". وفى رِوَايَةِ لأبى دَاوُد: "لاَ يُجْلَسُ بَيْنَ رَجُلَيْنِ إِلاَّ بِإِذْنِهِمَا".
'Amr bin Shu'aib on the authority of his father and grandfather reported: Messenger of Allah (ﷺ) said, "It is not permissible for a man to separate between two [people] without their permission." [Abu Dawud and At-Tirmidhi]. And in a version narrated by Abu Dawud "He should not sit between two men without their permission."
