—Abu Muslim wrote to al-Saffāḥ, urging him to put him to death; but al-Saffāḥ refused, saying, “He is a man who has staked both his life and his wealth for us.”
So Abu Muslim secretly dispatched men who had travelled with him, and they assassinated him by night in al-Anbār. He had just left an evening gathering with the Caliph when a group attacked and killed him. This took place four months after al-Saffāḥ’s accession, in Rajab of the year 132 AH.

The common folk claimed that the Khārijites were the ones who killed him.

He—may Allah pardon him—was known as “the vizier of the family of Muhammad.”

He lived in Darb al-Khallālin⦗1⦘, and became identified by that address.

Concerning him it was said:
Indeed, the vizier—the vizier of the House of Muhammad—has perished;
so whoever begrudged you has now become the vizier.
