Messenger of Allah ﷺ sent us on military expedition telling us, "If you find such and such persons (he named two men from Quraish), burn them fire." Then we came to bid him farewell, when we wanted to set out, he said: "Previously I ordered you to burn so-and-so and so-and-so with fire, but as punishment with fire is done by none except Allah, if you capture them, kill them, (instead)." (Using translation from Bukhārī 2954)   

بَعَثَنَا رَسُولُ اللهِ ﷺ فِي بَعْثٍ وَقَالَ «إِنْ وَجَدْتُمْ فُلَانًا وَفُلَانًا لِرَجُلَيْنِ مِنْ قُرَيْشٍ فَأَحْرِقُوهُمَا بِالنَّارِ» ثُمَّ قَالَ رَسُولُ اللهِ ﷺ حِينَ أَرَدْنَا الْخُرُوجَ «إِنِّي كُنْتُ أَمَرْتُكُمْ أَنْ تَحْرِقُوا فُلَانًا وَفُلَانًا وَإِنَّ النَّارَ لَا يُعَذِّبُ بِهَا إِلَّا اللهُ فَإِنْ وَجَدْتُمُوهُمَا فَاقْتُلُوهُمَا»
