[Machine] Abu Usaid al-Ansari arrived with a group of captives from Bahrain, so they were lined up. The Messenger of Allah ﷺ stood up and looked at them, and he saw a woman crying. He asked her, "What makes you cry?" She said, "My son was sold in 'Abss." The Prophet ﷺ said to Abu Usaid, "You may ride and bring him back, just as you sold him for the price." So Abu Usaid rode and brought him back, and if there was any payment for him, it was good and lawful because it was a valid transaction witnessed by what had passed.  

أَنَّ أَبَا أُسَيْدٍ الْأَنْصَارِيَّ ؓ قَدِمَ بِسَبْيٍ مِنَ الْبَحْرَيْنِ فَصُفُّوا فَقَامَ رَسُولُ اللهِ ﷺ فَنَظَرَ إِلَيْهِمْ فَإِذَا امْرَأَةٌ تَبْكِي فَقَالَ مَا يُبْكِيكِ؟ قَالَتْ بِيعَ ابْنِي فِي عَبْسٍ فَقَالَ النَّبِيُّ ﷺ لِأَبِي أُسَيْدٍ لَتَرْكَبَنَّ فَلَتَجِيئَنَّ بِهِ كَمَا بِعْتَ بِالثَّمَنِ فَرَكِبَ أَبُو أُسَيْدٍ فَجَاءَ بِهِ هَذَا وَإِنْ كَانَ فِيهِ إِرْسَالٌ فَهُوَ مُرْسَلٌ حَسَنٌ شَاهِدٌ لِمَا تَقَدَّمَ
