"When captives were brought to him, the Prophet ﷺ would give the members of one family together (to one person), not wanting to separate them."  

كَانَ النَّبِيُّ ﷺ إِذَا أُتِيَ بِالسَّبْىِ أَعْطَى أَهْلَ الْبَيْتِ جَمِيعًا كَرَاهِيَةَ أَنْ يُفَرِّقَ بَيْنَهُمْ  

"The Messenger of Allah ﷺ gave me two slaves who were brothers, and I sold one of them. He said: 'What happened with the two slaves?' I said: 'I sold one of them.' He said: 'Take him back."'  

وَهَبَ لِي رَسُولُ اللَّهِ ﷺ غُلاَمَيْنِ أَخَوَيْنِ فَبِعْتُ أَحَدَهُمَا فَقَالَ مَا فَعَلَ الْغُلاَمَانِ قُلْتُ بِعْتُ أَحَدَهُمَا قَالَ رُدَّهُ  

"The Messenger of Allah ﷺ cursed the one who separates a mother and her child, or a brother from his brother."  

لَعَنَ رَسُولُ اللَّهِ ﷺ مَنْ فَرَّقَ بَيْنَ الْوَالِدَةِ وَوَلَدِهَا وَبَيْنَ الأَخِ وَبَيْنَ أَخِيهِ
