It was narrated that `Ali (رضي الله عنه) said:
The Messenger of Allah (ﷺ) sent me, az-Zubair and Abu Marthad on a mission, and we were all horsemen. He said: “Set out until you reach Rawdat Khakh` - this is how Abu `Awanah said it - “and there you will find a woman who has a letter from Hatib bin Abi Balta`ah to the mushrikeen.” And he quoted the hadeeth at length.
