عَنْ أَبِي أَيُّوبَ الْأَنْصَارِيِّ رَضِيَ اللَّهُ عَنْهُ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ قَالَ مَنْ فَرَّقَ بَيْنَ الْوَلَدِ وَوَالِدِهِ فِي الْبَيْعِ فَرَّقَ اللَّهُ عَزَّ وَجَلَّ بَيْنَهُ وَبَيْنَ أَحِبَّتِهِ يَوْمَ الْقِيَامَةِ
Narrated by Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever, while trading (slaves), separates a child from his parents, Allah Almighty will separate him from his loved ones on the Day of Resurrection.
