Riyad as-Salihin 17:99

Abu Hurairah (May Allah be pleased with him) said:

The Messenger of Allah (ﷺ) sent us on an expedition and said to us, "If you find so- and-so (he named two persons belonging to the Quraish) commit them to the fire." When we were on the verge of departure, he said to us, "I ordered you to burn so-and-so, but it is Allah Alone Who punishes with the fire. So if you find them put them to death." [Al- Bukhari] .
