Question: Assalamu aleykum wa rahmatuLlahi wa barakatuh dear brothers. Help please with one hadith from Islamophobes: the Pre-lslamic Period of Ignorance there was a house called Dhu-l-Khalasa or Al-Ka`ba Al- Yamaniya or Al-Ka`ba Ash-Shamiya. The Prophet (ﷺ) said to me, "Won't you relieve me from Dhu-l- Khalasa?" So I set out with one-hundred-and-fifty riders, and we dismantled it and killed whoever was present there
Historical context and what mean "killed whoever was present there"?
Source <https://sunnah.com/bukhari/64/381>

Answer: 
First note that the hadith appears in Sahih al-Bukhari and therefore is considered as trustworthy by sunni scholars.

Secondly if you open Sahih al-Bukhari and read the next hadith in the same section <https://sunnah.com/bukhari/64/382> you will realize that Jarir and his hundred or hundred fifty companions demolished that "Deity and its house of worship". The prophet choose Jarir actually because he was from the tribe of Khat'aam who was living in that place. The 3rd hadith <https://sunnah.com/bukhari/64/383> in the same section also doesn't by any means say that he killed people without any opposition or unfounded, but that he demolished the place of worship of an Idol and called and invited them to Islam before fighting them. And so on ibn Hajar (see in <http://library.islamweb.net/newlibrary/display_book.php?idfrom=7852&idto=7857&bk_no=52&ID=2250>) quoted that al-Hakim quoted a hadith saying that Jarir جرير بن عبد الله البجلي was ordered to demolish the Idol (Dhul Khalasa) and the house of worship and to invite his tribe to Islam and to give them 3 days before using the sword against them and demolishing the Idol they were worshiping. So he didn't kill anybody unless they refused to refrain from worshiping other than Allah and/or fought him and his companions.
I don't know about thus report authenticity but taking women as war booty is part of Islam. Prophet SAW had a slave girl called Maria the Copt. A man does as he wishes with his property, it is allowed with the companions the right hand. remember Islam does not have to live up to disbelievers idea of what is good rather islam is what dictates what is good and what is evil. If the profit did it or approve of it then we accept it as good , full stop.
