Hadith #3

3- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ النَّوْفَلِيِّ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) أَنَّ أَمِيرَ الْمُؤْمِنِينَ (عَلَيْهِ السَّلام) قَالَ مَنِ اسْتَأْسَرَ مِنْ غَيْرِ جِرَاحَةٍ مُثْقِلَةٍ فَلا يُفْدَى مِنْ بَيْتِ الْمَالِ وَلَكِنْ يُفْدَى مِنْ مَالِهِ إِنْ أَحَبَّ أَهْلُهُ.

3. Ali ibn Ibrahim has narrated from his father from al-Nawfaliy, from al-Sakuniy who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said that one who turns himself into captivity without suffering a disabling wound is not ransomed on the expenses of public treasury. He however may be ransomed with payment from his own properties.”
