Hadith 10:285
‘Abdallah b. Mas'ud said that when captives were brought to the Prophet he gave families together through dislike of separating them. Ibn Majah transmitted it.
وَعَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا أُتِيَ بِالسَّبْيِ أَعْطَى أَهْلَ الْبَيْتِ جَمِيعًا كَرَاهِيَةَ أَنْ يفرق بَينهم. رَوَاهُ ابْن مَاجَه
