ذِكْرُ الْأَمْرِ بِالِاغْتِسَالِ لِلْكَافِرِ إِذَا أَسْلَمَ
[Machine] Thumamah al-Hanafi was captured, so the Prophet ﷺ used to visit him and say, "What do you have, O Thumamah?" Thumamah would reply, "If you kill, then kill a man of blood, and if you show kindness, then be kind to a grateful person, and if you take something, then give whatever you wish." The companions of the Prophet ﷺ loved to offer ransom and they would say, "What should we do with this man's killing?" One day, the Prophet ﷺ passed by him and he embraced Islam. The Prophet then sent him to the orchard of Abu Talhah and commanded him to bathe. He bathed and prayed two rak'ahs. The Prophet ﷺ said, "Indeed, the Islam of your companion is good."
أَنَّ ثُمَامَةَ الْحَنَفِيَّ أُسِرَ فَكَانَ النَّبِيُّ ﷺ يَعُودُ إِلَيْهِ فَيَقُولُ «مَا عِنْدَكَ يَا ثُمَامَةُ؟ » فَيَقُولُ إِنْ تَقْتُلْ تَقْتُلْ ذَا دَمٍ وَإِنْ تَمُنَّ تَمُنَّ عَلَى شَاكِرٍ وَإِنْ تُرِدِ الْمَالَ تُعْطَ مَا شِئْتَ قَالَ فَكَانَ أَصْحَابُ النَّبِيِّ ﷺ يُحِبُّونَ الْفِدَاءَ وَيَقُولُونَ مَا نَصْنَعُ بِقَتْلِ هَذَا «فَمَرَّ بِهِ النَّبِيُّ ﷺ يَوْمًا فَأَسْلَمَ فَبَعَثَ بِهِ إِلَى حَائِطِ أَبِي طَلْحَةَ فَأَمَرَهُ أَنْ يَغْتَسِلَ فَاغْتَسَلَ وَصَلَّى رَكْعَتَيْنِ» فَقَالَ رَسُولُ اللَّهِ ﷺ «لَقَدْ حَسُنَ إِسْلَامُ صَاحِبِكُمْ»
