Miqyas ibn Subabah

Miqyas ibn Ṣubābah was a non-Muslim of Mecca whose brother, Hishām ibn Ṣubābah, was accidentally killed by friendly fire during the expedition of al-Muraysīʿ (5 AH). Feigning conversion to Islam, Miqyas traveled to Madinah and successfully claimed a hundred camels in blood-money for his brother's death, a payment properly owed under Islamic law for accidental manslaughter. That same night, he murdered the Anṣārī Companion responsible for the killing in cold blood and fled back to Mecca with the camels, reverting openly to his former disbelief. At the Conquest of Mecca, he was named among a small handful of individuals the Prophet (ﷺ) ordered killed on sight without amnesty, on account of this act of treachery, feigned conversion, fraudulent collection of blood-money, and premeditated murder committed under the cover of Islam.
