According to Mohammad only the last words are valid - that is the Second Given half which is only knowable of you read the official Sunnahs and Hadiths: Talibari, Muslim, Isaq and Bukhari. The First Given half was based on or plagiarized from the early Bible and the Torah - a previous posted quoted from it, but those suras are not valid.
Another reason Mohammad abrogated the First Half is while that was in effect he only had around 150 followers and he was going nowhere. The Second Given half got things rolling with allah’s license to kill anyone not them especially Jews and Christian - later expanded to Hindus with that the jihad began led by Mohammad shouting, “Kill. Kill Kill” - his motto.
To his claimed ‘credit’ is his personal effort to behead over 400 prisoners. That’s a lot of work for this ‘Christ-like’ figure. Oh sorry, Christ didn’t kill anyone, but many in their ignorance believe the two are comparable, believing Mohammad is a ‘Christ-like’ figure.
This is correct.
The Koran is just the start of Islamic jurisprudence, which is the core of this extremely legalistic religion. Reading the Koran is not a good way to understand Islam.
