Musannaf Ibn Abi Shaybah 39391 — Reports on the letters of the Prophet

It is narrated from Qays bin Abi Hazim that the Messenger of Allah (peace and blessings be upon him) sent (a force) to the tribe of Khath'am on account of some people who were among them. When the Muslims closed in on them, those people sought protection through prostration (that is, they showed their Islam through prostrations). The narrator said: So those people prostrated. The narrator said: Even so, the Muslims killed some of those who prostrated. This reached the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) said: Pay half of their blood money because of their prayers. Then the Prophet (peace and blessings be upon him) said: Behold! Whichever Muslim lives with a polytheist, I, Muhammad (peace and blessings be upon him), am free of him.
