Musannaf Ibn Abi Shayba 28:728

Hafs ibn Ghiyath narrated to us, from Hajjaj, from al-Hakam, from Miqsam, from Ibn Abbas, who said: A man was killed on the day of the Trench, and the Muslims overcame the polytheists regarding his corpse. They (the polytheists) said: "Hand over his corpse to us, and we will give you ten thousand dirhams." This was mentioned to the Prophet, may Allah bless him and grant him peace, and he said: "We have no need for his corpse nor his blood money; he is of foul blood money and foul corpse."
