عَنْ عِمْرَانَ بْنِ حُصَيْنٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَدَى رَجُلَيْنِ مِنَ الْمُسْلِمِينَ بِرَجُلٍ مِنَ الْمُشْرِكِينَ مِنْ بَنِي عُقَيْلٍ
It is narrated from Sayyiduna Imran bin Husain (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) took two Muslims in exchange as ransom for a polytheist of Banu Aqeel.
