Sayyiduna Sahl bin Abi Hathmah (may Allah be pleased with him) said that a group went to Khaybar and found a slain man there; then he narrated the long hadith of qasamah (collective oaths), in which it is also stated that the Prophet (peace and blessings be upon him) disliked that his blood should go to waste, and he paid his diyah with 100 of the camels of charity (sadaqah).
