The Messenger of Allah ﷺ instructed me to sell two slaves who were brothers, so I sold them and separated them. I told the Prophet ﷺ about that and he said: ʿGo and find them and take them back, and do not sell them except together.ʿ
أَمَرَنِي رَسُولُ اللهِ ﷺ أَنْ أَبِيعَ غُلامَيْنِ أَخَوَيْنِ فَبِعْتُهُمَا وَفَرَّقْتُ بَيْنَهُمَا فَذَكَرْتُ ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَ أَدْرِكْهُمَا فَأَرْجِعْهُمَا وَلا تَبِعْهُمَا إِلا جَمِيعًا
