It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) "ruled ten dirhams" for a runaway slave who is found in the Haram.
Ibn Abi Mulaykah and Amr bin Dinar (may Allah have mercy on them both) said that the Messenger of Allah (peace and blessings be upon him) "fixed ten dirhams" for a runaway slave who is found outside the Haram.
The first report is weak; what is preserved (mahfuz) is the second, and it is munqati' (its chain is broken).
