Musannaf Ibn Abi Shayba 1:1077

1077. Abd al-Salam ibn Harb narrated to us, from Ishaq ibn Abi Farwah, from Ata, that a man had a wet dream during the time of the Prophet, may Allah bless him and grant him peace, while he was suffering from smallpox. They washed him, and he died. That reached the Prophet, may Allah bless him and grant him peace, and he said: "They ruined him, may Allah ruin them. They killed him, may Allah kill them."
