The Messenger of Allah ﷺ said to me, "Will you not relieve me of Dhul-Khalasa?"I replied, "Certainly."So I set out with one hundred and fifty horsemen from Ahmas. They were skilled riders, but I was unable to remain steady on horseback. I mentioned this to the Prophet ﷺ, and he struck his hand against my chest until I could see the mark of his hand on my chest, and he said, "O Allah, make him firm, and make him one who guides and is rightly guided."After that, I never fell from a horse again.Dhul-Khalasa was a temple in Yemen belonging to the tribes of Khathaam and Bajilah. It contained idols that were worshipped, and it was called the Kaabah. Jareer went to it, burned it down with fire, and destroyed it.When Jareer arrived in Yemen, there was a man there who used to seek omens by drawing divining arrows. He was told, "The envoy of the Messenger of Allah ﷺ is here, and if he gets hold of you, he will strike off your head."While the man was casting his arrows, Jareer suddenly stood over him and said, "You shall break these arrows and bear witness that there is no god but Allah, or I will strike off your head."So the man broke them and bore witness.Then Jareer sent a man from Ahmas, known by the kunyah Abu Artaah, to the Prophet ﷺ to bring him the good news. When he reached the Prophet ﷺ, he said, "Messenger of Allah, by the One who sent you with the truth, I did not come until I had left it looking like a mangy camel."The Prophet ﷺ then invoked blessings upon the horses and men of Ahmas five times.
قال لي رسول الله ﷺ: ألا تريحني من ذي الخلصة؟ فقلت: بلى، فانطلقت في خمسين ومائة فارس من أحمس، وكانوا أصحاب خيل، وكنت لا أثبت على الخيل، فذكرت ذلك للنبي ﷺ، فضرب يده على صدري حتى رأيت أثر يده في صدري، وقال: اللهم ثبته واجعله هاديا مهديا قال: فما وقعت عن فرس بعد، قال: وكان ذو الخلصة بيتا باليمن لخثعم وبجيلة، فيه نصب تعبد، يقال له الكعبة، قال: فأتاها فحرقها بالنار وكسرها. قال: ولما قدم جرير اليمن كان بها رجل يستقسم بالأزلام، فقيل له: إن رسول رسول الله ﷺ ها هنا، فإن قدر عليك ضرب عنقك، قال: فبينما هو يضرب بها إذ وقف عليه جرير، فقال: لتكسرنها ولتشهدن: أن لا إله إلا الله أو لأضربن عنقك، قال: فكسرها وشهد، ثم بعث جرير رجلا من أحمس يكنى أبا أرطاة إلى النبي ﷺ يبشره بذلك، فلما أتى النبي ﷺ قال: يا رسول الله، والذي بعثك بالحق، ما جئت حتى تركتها كأنها جمل أجرب، قال: فبرك النبي ﷺ على خيل أحمس ورجالها خمس مرات.
Bukhari narrated it in the chapter on military expeditions (4357), and Muslim in the virtues of the companions (2476:137), both through the route of Ismail bin Abu Khalid, from Qays bin Abu Hazim, from Jareer bin Abdullah Bajali, who said, then he mentioned it.
