The Messenger of Allah (ﷺ) sent us along with a contingent, and said: If you find so-and-so. He then narrated the rest of the tradition to the same effect.
Sunan Abi Dawud Book 15, Hadith 198
← Previous Hadith The Messenger of Allah (ﷺ) appointed him commander over a detachment. He said: I went out along with it. He (the Prophet) said: If you find so-and-so, burn him with the fire. I then turned away, and he called me. So I returned to him, and he said: If you find so-and-so, kill him, and do not burn him, for no one punishes with fire except the Lord of the fire.

Sunan Abi Dawud Book 15, Hadith 197 Next Hadith → We were with the Messenger of Allah (ﷺ) during a journey. He went to ease himself. We saw a bird with her two young ones and we captured her young ones. The bird came and began to spread its wings. The Messenger of Allah (ﷺ) came and said: Who grieved this for its young ones? Return its young ones to it. He also saw an ant village that we had burnt. He asked: Who has burnt this? We replied: We. He said: It is not proper to punish with fire except the Lord of fire.
